That would be one way to do it, that ('t involve a PPP problem.
The Richards profile has clearly been thru a lot of changes and merges, and I suspect nobody wants to open it up again, despite the obvious need for this. Perhaps someone who knows this history would explain how it came to pass and what the reasoning was for the merge, but it doesn't seem to be happening.
But since you (I assume) don't care about that profile and want to straighten out the other line, you should think about the ways to get this done.
What you don't want (I assume) is another merge. If you create a new profile for Alice, then you are the PM and it can't be merged without your agreement when people see the two profiles and say "They're the same person."
So H-25 should be divested of the parents you believe belong to the other Alice, so people won't be likely to think that.
To change the LNAB for a profile, you have to be a PM.
