I know we have boosters for this but as well as having those boosters that give small bonuses we can sacrifice a stat completely for a large increase of another. With our armour we have 2 tanks, jet pack and o2. Maybe we can have a slide switch in the armour screen to tradeoff between the 02 tank space and jetpack tank space. example I float in space building a CV, i set the slider to max oxygen, the oxygen tank is increased a significant amount for long space walk and the JP thrust tank for planets is now non functional, I will have to fill my oxygen tank up to meet the new capacity. When I reach o2 planet, I drag the slider to max Jetpack, I now have no oxygen capacity, the oxygen has been purged but significantly increased jet pack time is now available. And if i want to add some oxygen capability, I can still add oxygen boosters ! Player would lose existing oxygen supply when setting to max jetpack so will need to refill their tank. There could also be a trade off for radiation protection vs armour capacity. And maybe the higher level the armour the more tradeoff options there could be. Allowing for on the fly armour tweaking via the armours built in software. Boosters are added hardware to supplement your armours tweaking software.
