I'd definitely be up for this some week when it's Juggler+Brawler. The fastest I've done w normal runs is 42 min (not newbies but also not trying for speed). The big issue is all the built-in wait time, not just between rounds in the airlock but between waves and between objectives spawning. You'd want to make sure everything was dead by the time all mines dismantled in round 3, for example.
Round 2 would be interesting, how much risk you could take w jump-shot gunning the Major Hobgoblins to clear adds quickly relative to mine destruction. And I'm curious what the fastest DPS primary for Pilot Servitor would be, definitely need at least two Titans for bubble trains and Weapons of Light. Probably worth spamming GHorn to get Pilot down faster, although synth cool downs would be tricky to manage.
Anyway, fun to think about! Let's give it a whirl sometime.
