The compressor is 2.1 x 4.5 x 6, 57 cu in as a box. So it's pretty close on volume consumption. You'd probably be better off running 2 tanks and no compressor than 1 tank and 1 compressor. You'd definitely be better off running just 1 tank.

If you're more limited by volume than weight and doing such small shifts, you can do a compressor and a much smaller (metal) accumulator; I'd recommend something at least 3x as large as the combined volume of your shifter cylinders. You can get these from
Bimba or other sources. As a temporary solution (but as I read the rules not at competition) you can use the rod (retract) side of a medium-sized cylinder as an accumulator. There are probably also smaller plastic accumulators out there, but I haven't searched.
