Interesting! Setting the weight of the compressors and the energy requirements (I guess you could supply that ground side if possible) it really does solve the issue of loosing helium. :) For hydrogen you I guess you could either let it go or also use the compressors in case there is no way to replenish the lifting gas & you might need the extra lift before returning to your primary maintenance base.
