I think my system would work very similar to yours. It may take more than a couple of heat cycles due to no swirl pot, but when air comes out, it is trapped and only coolant can return. I always check the fire extinguisher after an engine run and after a while??? Don’t have to add more coolant.
Where does one come across an RX-2/3 pressure bottle??
Probably no more available. I would make one from an expended fire extinguesher bottle. TIG on a plain pressure cap throat. Pick one that works with a 22 pound cap. The stuff welds up real nice and can be polished. Close to zero weight.

I welcome comments on this set up.
