Q: How do Alternative Abilities and Compartmentalised Mind interact?

A: While this may not be evident from the RAW, Kromm spoke thus:

All mechanics that make abilities cheaper do so under the assumption that they'll actually limit the character. Making CM a one-stop shop for working around such things makes it a one-stop shop for cheesy abuse. It might seem fine when you're paying 50 points to get around innate usage limits on a cheap ability . . . but what happens when someone takes Ability 1 [1,000] and Ability 2 [1,000] as alternative abilities, pays 1,200 points, drops 50 points for CM 1, and enjoys 2,000 points of abilities – along with all the incidental benefits of CM – for just 1,250 points? That would be a crock.

Thus, the answer is a definitive "No way!" The main benefit of CM is extra actions. That's what 50 points fairly buys.
