You should be able to fit bridges with similar dimensions as an OFR into the cavity of an Edge-Pro equipped guitar. The Edge-Pro itself isn't the worst bridge for the job if you can find a cheap replacement but that might be hard depending on where you're at. Barring that, I wouldn't go with the cheapest FR you can find but you'll probably be okay with something middle of the road and just do as solid of a block-job as possible to eliminate any extra movement you might come across to reduce wear on friction points. You can always get a cheap bridge and upgrade the saddles and maybe the sustain block at some point if its upgrade-friendly.
