I've done the reverse, Edge studs with a Floyd Rose. It SHOULD work, though I'd caution you the Floyd Rose studs are likely harder than the Edge ones, and you may wear the knife edges abnormally fast. I haven't had any issues, but the OFR7 I'm using is definitely harder on the studs than the LoPro it replaced (which was falling to peices).
The OFR is actually a really great trem - my suggestion would be to grab one of these:
...which fixes the one disadvantage of the OFR over the Edge, and give it a shot.
