Elastigirl model Swap or Head Hack?

Been debating for the Omnidroid vs Elastigirl Scene if I should replace the original model with the more movie accurate one, but that would mean losing the very nice plump body of the other one. So i thought to combine the two and I wanted to ask what people think! is this a good way to go about it to have best of both worlds or would you rather sacrifice one over the otherNote: This will also be for the Droppod animation as well :))
