Unilug wheels - Do they fit the small bolt pattern?

I've got some Unilugs, don't know if I can use 'em yet, but I've been thinking of tossin' em on the drill/ mill and redrill the pattern "halfway between", then turn a decorator ring/ bezel to cover up the holes.

That would allow you to use "real" lug nuts and no washers

In fact I damn near bought some chibby Ansens awhile back to try this out on.
