I am assuming he more wants to know if it is a rare/classic enough game that it would be a "sin" to not bring it back to it's original Xevious glory.
I'm no Xevious expert, but I am pretty sure that it was a common cabinet. If it is the cabinet I am thinking of, then it had great art as well, and I personally hate to change cabinets will full body side art as long as it is still in good condition.
What you might consider doing is making a Xevious themed mame cab out of it. Keep the existing Xevious art, and make a custom Marquee and Control panel that looks Xevious-esque. If you ever feel the need to later bring it back as a real Xevious, you wouldn't have harmed any of the current art.
