Classic Rogue gets to add 3 more mutants to her power set

[FennerMachine]

Classic Rogue, with Ms. Marvel powers, gets the opportunity to add 3 more mutant's powers to her power set permanently but without permanently affecting the 'donors'.
Who would she pick?
Who would you pick?
How powerful is the new Rogue?
Would she be OP, making a noticeable different against larger threats such as Apocalypse, Mr. Sinister and against other teams of mutants? Or would she be at roughly the same level but with additional abilities and provide a 'bit of an edge' that the X-Men didn't have before?

Depends on your definition of mutant.

Thanos is a mutant I believe. I think Black Bolt is too.

Ignoring those, and just using human mutants, she can pick Vulcan, X-Man, and Franklin Richards.

She becomes the most powerful being in Marvel universe short of the Living Tribunal.

EDIT: She can pick just one of those and easily handle all classic X-Men villains.

Black Bolt is an Inhuman, not a mutant.

I know that. But I thought Inhumans were Kree mutants.

Really? I never heard that.

Oh yeah. Forgot another one she can take. Post-retcon Beyonder.

Wanda and MJJ are mutants as well - let's throw one of them in with Frank and Nate.

Limit to human mutants or ones she could realistically absorb according to feats.
Some, such as 90's animated Apocalypse, she has 'slight' trouble absorbing!

Even if she just took say...Xavier, Emma, and Jean, that's 2 alphas, and 1 omega. That's more than enough to stop probably all of Earth's heroes/villains.

Or Xavier, Magneto, and whoever, that's a weak Onslaught right there.

There's a reason he's called Post-retcon Beyonder. He's retconned meaning he doesn't exist.
