Re-size some models?

Hey there, I don’t tend to not be here much, but I decided to come out of my shell with a request. I am currently brainstorming ideas for a Gmod movie I want to do. I need the Ikaruga model from the MMD Misc. pack to be re-sized in giant and small versions. I have found some giant models of Ikaruga, but the face poser breaks at certain point. While I can work with these I would like to see if anyone can make them as big as possible before the facials break. This is only optional. What I need most of all are the small versions of the model.

Hope you guys help me out. I’m a bit nervous when it comes to posting on new fourms.

Here are the models incase you need them.

Sorry for the bump.
