as far as I know there in not any 90 AIO
that said I have the SCA 90 tank. I call it my little big tank. the most volume i could find in a small foot print 36x24x24 if/when moving I thought I could always find a spot for a 3' tank.
the tank is built like a tank.haha but it's heavy to move a 6' 125 or 180 is lighter. that's what you get for having 12mm low iron glass.
what size is your nano?
maybe a 4obr might do the trick ?one of my fav. size tanks to be honest. or a 57 rimless if you want to go fancy.
I know how it is knowing in the future you will be moving but trying to have a big tank. I once have an 8' 240 that was lighter than my current tank. and easier to move.
I would put some real thought in to this. if you are going FOWLR maybe just get what you want now? be pretty easy to catch the fish and keep in bins.ect. while you move the aquarium to the new place. as long as you have overlapping places that is.
also one size/style might be perfect for one house but not the other...
good luck!
