I do not think you are saving any weight over nearly all pumps.
Carry CO2 and you can get away with a smaller pump.
GI Microflate Nano weighs ~25 grams. Lezyne 170mm mini-pumps weigh ~90 grams. Combine them and you've got the speed and convenience of CO2 and and the reliability of a pump, with each being a backup for the other. Lighter in total than 3 cartridges.
Weight's not that important, but might as well save it if you can.
