Nope. Rumple is the most powerful non-deity person in the Once Universe. Ingrid is no match. Rumple doesn't do much because he doesn't like be showy.

Hyde cannot be killed. Ingrid would fare no better than if Regina tried an immobilization spell on him (which they haven't done yet to him or EQ). Hyde is immune to physical damage as well and would just reform. Rumple, Regina, Emma, and Zelena could easily kill him, but he'd just reform and that's a waste of time.

And no Ingrid is far weaker than Rumple. Ingrid only stands up when she has hers, Elsa's, and Emma's combined power. And he still threatens her and gets away with things.

Ingrid and Elsa might be frequent big splash damage dealers, but their magic is quite frail. Regina easily destroyed Marshmallow. If Ingrid wasn't regenerating her ice Viking, Emma would have easily defeated it herself. So at best, Ingrid and Elsa would slow him down,but that's essential ally what everyone else is doing.
