parallel board/harness charging help, please...

Hey all,
I am having a hell of a time trying to figure out how to make this work for me. I will give you the scenario.
dual output 10A / 100-200 Watt charger w/ a 47A 575W juicebox PS.
I am trying to figure out how to charge 1 X 2800 mah 2s protek tx lipo batt and 3 X 2000 mah 2s protek rx lipo batt on each output. This would be a 8.8A 1c, and consume approx. 65watts per channel. 2s4p 8800mah batts.
The batts have XH balance connectors, and JR charge connectors.
I have looked for parallel boards that have the Jr female charge ports on the board, but haven't found anything. I also looked into making my own harnesses, but run into amp and gauge wire size problems. for a 8.8+ amp load, you need to run,at least, 18 gauge wire.
I thought about making XT-60 to Jr female leads, but think 18 gauge is too big for the Jr's and too small for the XT-60's? I looked into also purchasing harnesses, but all the Jr female connectors have 22 gauge wire, at the largest.
Could someone help me figure out how to get either a harness built up, or a board that will do what i want?

For that gauge wire, you would need to make adapters. This is as close as I could get. Just need to make adapters.

I'd try contacting Progressive RC. I don't see what you need listed, but they make a wide variety and have great service, might be able to set you up. In general they have both parallel board and harness options.
Another possible source is Buddy RC.

Well, thanks all.
I was thinking about these items... Will this work?

Would the JST plugs be easier to solder with the 22 gauge wire? Are the XT-60 plugs not able to take that small of wire effectively? I could make extra long stripped ends and fold them in half if I need to.
Does anyone know if I could use 18 gauge wire on JR female connections, or is it too big, like i am suspecting it is?
Would 8.8A be too much for 22 gauge wire?
