The procedure is very similar to a trs-edge conversion;
You'd have to replace the anchors and enlarge the cavity around the trem.
So, if your good with a router and woodworking tools, check the following tutorial:

.
PS.
actually the edge (pro) does
not "kick the crap outta the ofr". So if your ofr is worn or broken, you should just get a new one.
