I don't remember where I saw this request, or if it's already in the game in some form, but I started over again recently and I got to the Stellar Tether quest. I just beat Tam and I thought, wouldn't it be fun to give her back her drone after you (eventually, maybe) spring her free from Gastigoth as part of a questline to gather as many allies as you can to fight the taint. Besides, at that point in the game, we're likely going to be swimming in as large an amount of drones possible. Getting rid of an old drone that is likely to be outclassed by another one.
Also, I would like to see more drones in the game. How many are there now? 4? There's the Tech Specialist drone, Tam-Wolf and its stages (damaged, repaired, 2.0), Siegewulfe and its iteration (regular, bimbo, bimbo domme), and a shelter drone which, if I'm not mistaken, doesn't actually count as a drone in the "replaces the Tech Specialist's drone" sense.
