Mod existing cab or start over?

[wraunch]

I have a 4 player Konami cabinet.  It was originally a TMNT cab that was converted to the great b-ball game Run n Gun.  I have gutted it and there’s some cabinet damage.  The biggest issue is taking all vinyl off and leaving it clean to revinyl.  I am going to drop a 4 player setup back on it running a raspberry Pi 4.  I need to find some CP layouts as the TMNT cab only used 2 buttons and I’ll have 6 for P1, P2 abd 4 for each P3, P4.  I also need artwork for the cab.  I think I want to go custom and put my family name on the Marquee with a bunch of game characters like Pac-Man, galaga, street fighter, etc.  where should I go to find CP plans?  Where can I find artwork that might work?
