Hmm Tau lore is a bit of a blind spot for me. Is there any precedent of a space marine piloting a Tau mech suit?

They are alright, they suffer from having large bases which makes them a pain in dense terrain. Lychguard probably do the job better. I like wraiths too because they have fly ability but do less damage and cost more

Viable in the sense that you can make one? Sure. Viable in the competitive sense? Probably very hard
