But the whole point of doing the campaign is having the jailbreak be part of the campaign. What's wrong with starting them at 1st level? They'll have NPCs with them, if difficulty is an issue.
This:
I thought about doing that, but I don't think I'd be able to do 2-4 level ups in a single session. Although I could divide it up, but that would require quite a few sessions.
I still think start them 2 levels below meet-up level, then do a single double-level-up session with each group.
The issue with having a player from one team help by DMing the other team is that the "DM-player" will gain too much out of game knowledge.
