[Question] Resizing .m2's without Glitchy's?

[Andrige]

Is it possible to resize a .m2 to a new size without as in the case of Glitchy's MES get a model anomaly that the model does get larger, however the walking and running animation speed does not match the new size, hence it starts 'moonwalking' and each step slides a bit since it's not in sync.
Also, I'm not wishing to use mefix.exe for this, I'm asking if there's a way around that.

Here's the model I'm talking about that I use for Dire Bear form... however, upon entering the form in-game it shrinks considerably so I want a way around that.
