OK, here's what I know. MC on this site has MB Predators, 16x8s, that fit, but the correct size has been sold out for awhile. It's worth a call to the company.
There are some wheels on tirerack.com that they say will fit. As far as I know no one has tried them yet, but there's a thread about them here:

Walker Evans and similar racing companies make 17" beadlocks (and look-alike "beadlocks" called streetlocks) that would be customized to fit, but they would be expensive and in my opinion too heavy. Other custom options are a possibility.
There are threads scattered throughout this site dealing with this problem. I just pulled out the stops looking for aftermarket 16x8" wheels and went with ProComp forged wheels that didn't clear the calipers, but could be made to fit with modificaitons.
Other than looks, the big reason for new rims is to upsize. 285 75 16 tires seat best on 16x8 wheels, while our stocks are 7". But unlike with most other vehicles, fitment is a huge problem for us because of the odd backspace and thus contact with the brake caliper.
