I'm sure when it's a new chapter, that the national reps who are picking the colonizing members take the opinions of the sisters from Mystery U into consideration - after all that's partly why they were brought in - to give a student POV so that it's not just adult volunteers picking the girls for the new chapter. Plus, chapters that are brought in to help recruit are usually ones that national HQs would like to have clones of, so I doubt they would discourage that from happening.

However...

As far as helping a struggling chapter, it probably results in a lot more "WTF?" than anything else if the Mystery U girls are actually rushing rather than kitchen-ing or decorating, and as IP said, doesn't go well. It's two very different situations.
