There's a pinned thread on bridge route compatibilities at Jemsite that might help:

In the case of putting a Lo Pro Edge into an OFR route, one concern would be that the Lo Pro Edge (like original Edge) is symmetric around the posts, extending equally far on both sides, whereas the OFR is not. The OFR is wider on the side holding the trem bar. So that side would definitely be wide enough for the Lo Pro Edge, but I'm not sure the other side would be, as it's pretty narrow. I'd check the Warmoth route measurements for the OFR (I think they post this info, but not sure if they give full dimensions for all parts of the route) and compare to the dimensions of a Lo Pro Edge. I'm doubtful that the Lo Pro Edge will fit without a little work, but if you're comfortable widening the route on one side by just a little, it should be pretty easy. I've done this with a Dremel to go between OFR/Gotoh1996t and Edge/Lo Pro in both directions. My results, careful as I try to be, will not pass for a CNC or factory route, even with some touch-up paint in there, but it works great and isn't a visible location when the guitar is assembled.
