Nothing wrong with having diverse influences IMO. However, it depends what the guy and the other members want out of the band.
If it's about creating something unusual then maybe he's all about bringing in a range of musicians, seeing who is good at what, and taking it from there. You might get something really interesting and creative out of it, but it would probably not have mass appeal and not many gigs, much less catapult the band onto the front page of Rolling Stone magazine.
If it's about getting a load of gigs and creating something bog standard to appeal to the great unwashed shambling herd, then maybe he'll end up with a revolving door of dissatisfied musos, because he should have put his cards on the table in the first place.
Further investigation would be good to try and get a bit closer to finding out what the plan is. Could be great. Could be terrible. Don't know unless you ask, I guess.
