I've done the rear reflector to LED conversion and there is a ton of room behind the rear cladding, but you do have to cut out some cladding that is behind the reflectors. Also, I haven't done the angel eye head lights, but I have converted the front marker lights to fog lights with angel eyes.

I can't find the thread right now, but LittleBeast has gone to projector beam headlights in the stock head light buckets. Pretty slick.
