I don't think the author needs to go to such lengths just to support some proprietary fonts, specially considering that there are great free and open options.
Sure, but that's not really an answer to the question!
You seem quite interested in the answer, so surely you can spend the required time reading the ToS of the various fonts yourself.
Please come back and let us know what you find!
It probably would. Redistributing the font in another form is usually a violation. It’s also severely impractical ;)
