I'm installing two floor drains in my 32 x 44' thickened edge slab. Slab is still not poured and I still need to add 5-6" of stone inside my forms before I'm ready to pour. Should I wait until stone is in place before I install drains or try and add them first?

I know I'd have to dig part of a trench in the stone but stone trench would also help hold everything in place.

I'd get enough stone in that they're full supported, and everything around and below them is compacted already. Really, either way will work, a little trenching in compacted gravel never killed anybody.......
