I just measured my panel, here's what I noticed: It's 25 inches wide (okay, I already knew that), the leftmost joystick center is 3.5 inches from the left wall, while the rightmost button bezel is only 1.5 inches from the right wall. Makes sense: you need more clearance room for the joystick than the buttons. And it doesn't look wrong or off in any way. So I think it'll look okay. But do a mockup, of course. You'll get your answer that way for certain.
