Disney Store Prince dolls head switch?

[SetsunaKou]

I've been wanting to transplant my Prince Hans from Frozen doll head onto a Mattel (Barbie) Ken Model Muse body but the head types don't match. I would need to trim/carve the excess 'neck' areas off the Hans head since the Model Muse body already has the full neck nob.

Is this possible? Has anyone done it before? (Not Hans in particular, just a Disney Prince head or even an older Ken head that has the plug in neck style rather than the movable knob/swivel style.) I recently did this for a 10th Doctor doll I made for my sister's birthday in August and he came out pretty decently but....the Disney doll heads are little larger and not sure if it'll work as well?
Plus, Hans is pretty rare so I don't want to cut him up if it's a failed mission from the start. ^^;;

Any thoughts, advice, or photos of similarly modded dolls? ^^

Edit: Just browsed eBay and found this doll---I bought him.

He appears to have the neck type I need for Hans (plug in) but I can't tell for sure, however, he was such a good price and the pale skintone, I took a chance.
Anyone here know if he has the plug in neck? Looks like it....^^ *hopes*
