The second evap should be parallel with the first.
Your compressor (if healthy) will be fine , it will keep up.
Most systems use an orifice tube for the front and an expansion valve in the rear.It is a little easier to fill/diagnose a system with that combo as the orifice is a constant and the expansion valve is a regulatory type device.
If the front has an expansion you could run the orifice in the rear, but the rear may cool better/ faster untill the system gets stabilized after a few minutes of run time.
You can run expansion valves on both ends if you like ,but it will be a little trickier to arrive at the correct pressures / charge amount as it would take a little more time for the temp/ pressures of the system to stabilize.
Super Nifty Woody BTW.
