1) The flop tube does not rely on the state of completion of the wings, it is dependent on the tanks being done. The short answer is, You can add a flop tube to a completed tank, but it will be tedious/difficult. If you were to add a flop tube to a completed tank you would have to take out the access panel on the interior rib. That access panel will include the fuel pickup and the fuel sender unit (unless the tanks have capacitive senders). Removing that panel will allow you some access into the tank which is where you would install the flop tube ? after drilling a hole in the forward tank/wing support for the flop tube fuel line to pass thru. You would also have to re-locate your fuel sender unit to the rear baffle location in the next inboard bay so that there is not interference from the flop tube. (unless you have capacitive senders). Like I said, not impossible, but not a lot of room to work within the closed up tank.
2) Yes, from what I gathered when deciding if I was going to run a return line, there are lots of fuel injected engine options that do not require a return line.
3) That being said, it is not difficult to add a return line after the tank is closed up?much easier than adding a flop tube.
4) Aileron trim is added to the fuselage ? there are no wing parts for aileron trim
