Classic, I call BS on this.
1. The reason that all 4 player control panels built today and as far back as over 20 years ago is because angling the outer players gives the two inner player more shoulder room. If you make all player's controls straight across it will require a larger than 48"W panel (most likely 54" at least) to fit everything and give all players the same space to play as the angled 48" panels. We have built 100's of 4 player player angled panels and have not had 1 complaint on the playability and function.
No, you don't want it straight across. You want the actual
Joystick base to be straight mounted like all the midway style 4-player cabinets. Placement stays the same, joystick orientation is straight like P1 and P2.
No need for a new "wider" panel.
2. If you want the player 3/4 controls moved up to the extreme top of the panel like in this picture you sent it will cause player 3/4 to have to reach up and over player 1 and 2's controls making play uncomfortable for all players. The owner of the cabinet "Pierce's Arcade" complained of this after we built this machine with these controls this far up (although he also made this request and later regretted it)
Where is this coming from? They don't need to move the controls...the joystick base just needs to be re-angled.
3. The reason the street fighter's buttons were so close together is because of the space limitation problem Capcom had with the normal 19" monitored or 25" monitored cabinets. They had to fit 6 buttons in the space normally allotted for 2 buttons on these classic cabinets. Normal button spacing for us and most arcade machines back in the good ol days were at 1.5" center to center from one button to the next. This is the most comfortable layout for ADULTS hands to play at and how we and many other cabinet manufacturers today build their machines for Adults.
Bovine-feces. I can see how this would pass by someone who is unfamiliar with arcades, but it ain't gonna fly here.
A majority of Street Fighters were conversion kits, that were installed into Dynamo cabinets. There is also the Big Blue cabinets that I believe were commissioned by Capcom at a limited run. I'm a little foggy of the history, but I do know that their reasoning is false.
There is no space limitation for in the CP for 2-player 6-buttons.

Does that look like they had problems with space?? Look at the button spacing, nice and tight, ergonomically placed.
Believe me, if you play on the current placement for a while, you will definitely develop hand cramps/strain.
4. The majority of players playing these Street fighter cabinets back in the day were children with smaller hands. Cramming all 6 buttons next to each other at less than this 1.5" C-C spacing will be uncomfortable for all ADULT players and will feel very cramped.

That's not true at all! A majority of players were children??? WHAT.
First, most arcades I've seen back in the 90's had people of ALL ages. Teenagers to adults mainly.
Second, look at the natural spacing between your fingers when at a rest... does that look like 1.5" wide to you? Maybe if you were Shaquille O'neal...
To rebuild this control panel will take weeks, I have about 30 custom orders going on right now that have a Christmas Deadline.
Weeks? Maybe 1 week, but weeks?? Perhaps it'll take that long to fix the other 30 custom orders altogether...but people here are able to cut a new CP, plexi and apply the art in less than a week, I'm pretty sure of that. Heck, I can do that, and I don't have a proper workspace or the toolset these guys have.
I just finished your new paint on your new control panel box and we had planned on finishing your machine up by Friday.
This will push this finish time back by about 2-3 weeks by the time I have new artwork mocked up, approved again by you and shipped to us. Then we will need to rebuild an entire new control panel box (wide enough for 4 straight player controls) and a whole new control panel and rewire everything.
It doesn't take long to rotate 2 of the joystick graphics, and squish the button labels closer together. He thinks this is going to take long because of the "straight" placement of P3 and P4, which isn't what you're asking for.
I mean, with paint drying time, I can see this taking maybe 2 weeks. Re-cutting/drilling/slotting the wood and plexi shouldn't be more than a couple days. Artwork changes -- an hour tops.
Here, I don't know if this will help, but I did a quick photoshop edit of your photo you originally posted. Buttons placed closer together, and P3 and P4 joysticks indicators: angled to match the P1 and P2 sticks.
