You could have a problem doing this.
Because fuel can flow from one tank to the other if you allow the gas level to go below the tank fill connection (about 1/2 tank) one tank could go quite low if you are going up or down hills and then your fuel tank could suck air and your engine would die on the road.
You could get around this by installing two electric fuel pumps, one for each tank (either in-tank or external) and connecting them with a relay that would switch from one tank to the other using your dash mounted Main/Aux switch.
