Ah, 'Tis a good model indeed but 'tis not mine, nor is it a default model to reskin :c
Thus you'll have to ask him to make a reskin of it rather than I, as I'm but a simple beginner in every sense of the word!
So aye, I can't make a version of his model without breaking the rules of the site, and I can't ask to use his model only to upload a blue version, as it would be dishonorable, whot.
