This is possible but you would need a different type of adapter due to the way these PCD's overlap one another.
Something like this is the most recent type:

There's another type which look this and have been around longer:

Just google custom PCD adapters and go from there, it's more than likely that someone will be able to make a set of these, email all of the major companies that come up.
If not redrill the wheels to 4x100 which is a more desirable PCD anyway, plus the centre caps hide the redrill BUT the wheels have to be flat backed to redrill.
Yes you could just redrill to 5x120 but some holes will overlap which then brings safety into consideration.
