Answer 1

8 лет фронтэндю. Первый раз вижу такое странное желание... =) Зачем? Смысл?

Answer 2

Web fonts are not merged the way you want them to be (as far as I know, which seems to be pretty good). They are connected by handles, the process can be automated (you have already been advised how). There is no point in converting to base64.
