Unfortunately not. It sure would make it easier, there is a pile of 15x6 rims out there.

In rough measurements the 16" factory wheel centers are 15.625. The 15" factory centers are only 15.125". All 16" aftermarket hoops are 15.5" in the valley. They can't build the feet of the 15" centers up enough to work.
When using the 16" centers they actually turn them down slightly so they will fit in the new hoop. They then lay a big bead of weld behind the foot to strengthen where it was machined down slightly. Finally they press them in setting the back space, true them up, and weld them in.
