do you think there would be any issue if I Tee'd the return line to both of my new tanks?
If I understand your situation, you have only two tanks on either side of the centerline, and no day tank.* If that is the case, then the simplest installation would be to replicate the tank combiner tee you already have and feed the power plant from that.* With them combined, as they should be to maintain trim, it is immaterial where the return line goes because you effectively have a single tank.* Put shut off valves out of each tank in case you want to isolate the tanks for some reason, as well as a drain valve for sediment removal.
