I say go for it. The #1 thing about hardcore for most guys is that they want to be imagine themselves in the place of the guy in the vid.
Take everyone's fav reality site bangbus. There was a "real" type situation that most guys could go "yeah, I could do that" and it was a huge turn on.
Now... guys in wheelchairs don't get that. They see bangbus and are still thinking "I wish I could do that."
I personlly don't see it as profitting off of them, I see it as including them in on something.
I mean... they shouldn't be allowed to do porn because they had an accident or something and ended up in a wheel chair? Screw that.. if a guy is good lookin, has a dick that works, and can get it up and finish the job on camera.. then film the guy. Regardless of whether he can stand or not.
All guys will get off on it... but more so... guys in wheel chairs will be thinking "hey, that could be me!"
