I've seen this done with body dropped trucks.
As for the 6l80/6l90's, I believe they are the same dimensions externally, so it won't make much difference in your floor clearance. You've already cut more than I did. I was able to put it in with a high hump. Another member on here has a 6l80 that he put in with a slightly massaged low hump, but we're both using factory frame and cross members.
I assume you have a truck or van engine/trans combo in there if you have a 6l90. You might need to swap your oil pan and possibly trans pan for more clearance so you can lower the combo in the frame. It appears you're only options at this point are to drop your engine/trans combo or make a new floor section. I might not be seeing something that may give you a third option though. Good luck!

Yeah that big ol 3inch block is currently sitting on top of the trans mount between the trans mount and and the trans itself, seems extremely strange.
My first thought was that the combo is just too high but as it sits even using a holly extra front clearance swap pan the engine will barely clear the rack and pinion.
The trans pan with the truck laid out on the frame is only a fingers thickness from the ground also as it currently sits. If i remove the spacer block the trans ends up sitting at approx a 10degree angle which is way too much, most id even be remotely comfortable with is 5degrees.
It definitely wouldn't clear with just the high hump alone as the damn yolk doesn't even clear the cab yet, the middle of the output shaft is right about where the floor pan is. Currently the engine is an LQ4 6.0 and the trans is a 90e from a 2007 2500 Truck,but these are just for rough mock up as the actual combo waiting to go in is a 2013 LSA/90e out of a Camaro ZL1/ Cadillac CTS-V.
As of right now i think my only options are to run a tunnel all the way through similar to a body dropped truck as you stated
Edit-Just took a second look and I guess the middle of the output shaft isn't at floor level, but that doesn't really make a difference as the top of the shaft is still at floor level.
