Possible? Yes, practical? No. The projectors that come in those are pretty poor in quality compared to say morimoto retrofits. you'd have to cut the projector out, mark on the new headlight, dremel the back out to fit it, then use jb weld all over, pray you pointed it correctly, hope you can find a shroud to fit, then hope it doesn't leak! Granted, it may not look quite as cool.
Personally, I'm a fan of the retrofits. They're better made projectors, and they're brighter to boot!
