Yeah, rear wheel is always going to have more lateral flex. I have an article that shows they are typically 40-60% more flexible (laterally) than the front wheel.
I haven't tried it myself, but a stiff rim and plenty of spokes on the back should help.
Oh yeah, flange spacing on the rear hub matters. You want as much distance between them as possible.
