Wx-78 rework discussion

I think it be cool if wx's upgrade perk was more fleshed out, so instead of just eating gears to get some boring stat upgrades, you could use the gears to craft cool modules and have more unique and versatile upgrades, each with their own unique upsides, or even some downsides. Could have a certain amount of upgrade slots you can use and each upgrade uses an amount of those slots till you run out, maybe have a unique structure that refunds you all or some the upgrades for reallocation. 
Some cool upgrades could be stat upgrades (of course), but also stuff like an armored chassis for some passive natural armor, or leg augments for faster speed. they could have some downsides too, like the stat upgrades may raise one stat but lower the other 2 a bit, so upgrading all of them isn't as good as focusing on one or two. The chassis could lower your speed a bit, or the leg augments cause your hunger to drain faster. Would make him a lot more interesting to play and more versatile to a team without having just godly stats with super speed (super speed can stay probably). Wonder what other cool upgrades he could have...
