I'd say you'd probably get away with it if you had a decent-quality closed-cam skewer like the ones Shimano use. I've got one clamping the back wheel of my main bike in place against the chain tension from a 26-tooth granny chainring, with horizontal dropouts, and it doesn't slip, so I'd say it'll clamp a derailleur on just fine if you do it up properly.
There is a chaintug-style tensioner for track rear fork ends available that has a derailleur hanger built into it. I can't remember who makes it.
It wouldn't be terribly "quick" to fit or remove the wheel with that setup though, as you'd probably have to take the chaintug off to get the wheel out of the frame, and putting the whole thing back on again while dealing with the spring tension from the derailleur trying to rotate the chaintug would be a pain in the arse.
