Yeah I really don't see a 27" tall tire working in the front. The only stuff I've see that tall up front was on drag cars, so, super narrow tires on narrow rims that were inset pretty far away from the fenders. If you've got a new reproduction 15x7" rallye with a 4" or even 4.25" backspace that tire is going to hit the lower front corner of the fender at least, and probably other things too.
I ran a 225/60/15 on my Duster with the BBP mopar disks up front and 15x7's with a 4.25" backspace, and even those didn't have much clearance. A little bit wider than the 215/70/15's, but a whole bunch shorter. And the height was honestly a bigger factor than the width was.
