Personally, I don't really think that it is possible...
For instance (even though this was my first year in FRC), I know that many of the drivetrains we saw used in Breakaway would not be a good fit for lunacy, and vice versa.
Specifically, lets look at swerve drive. All the pictures I've seen of swerve drive from games that are not Breakaway, have very low ground clearance, like 221's drive (not sure what year this was though):
If a team wanted to use that in Breakaway, they would need to use the tunnels, but a drive like that also doesn't leave a lot of room for a kicker, or lifting mechanism. Thus, you make the robot bigger, which means it has to go over the bumps. But that frame won't let you go over the bumps, so you have to raise your ground clearance, a la team 2108:
