IMo David too many things come into play on an electric for you to just build a guitar, then decide afterwards what bridge to use. Since different types of bridges , from strat hardtail and trem version, to a leo quann badass wraparound to a tunomatic are all different in hieghts, the neck angle, or the depth at which the neck is set must change.
I built my last SG style electric using a Gotoh wrap style, approx 11mm high, similar to the PRS bridge. Its about as low as you can get with that style. Any other wrap or stop/tunomatic is higher by about 3mm I think. Depending on the trem bridge, you might find something that will work at the same neck angle, but you will just need to search out different types. Most spec sheets dont give the overall bridge height either, you need to measure them in person (ie the Gotoh or SM catalog doesnt tell you what the heights to the saddle peaks are) or is you need some clearance if its a wrap - like the one I used does need clearance, you cant have it sit on the body or you cant changes the strings .. hey that might be a useful feature for some players !!
