from scratch or as retheme I think the concept would work. there are lots of biker bars in every state and plenty of individuals who'd want. the concept could be good in a strip club for a few drinks eye candy and pinball, nevermind the lapdance thanks..
not trying to stereotype, the "niche market" is likely a lot larger than many might think.

agree scantily clad provocative poses and expressions is plenty for the artwork, let the music and callouts be the PG-R-X rated options for the concept.
somewhat x rated tunes? (yeah maybe NSFW)

gameplay unlocking music and videos to cause distractions and ball drains?
if its going to have a subwoofer, might as well work it a little bit.
