Hi Philipp, Yes, something like that should work - it's more or less how most live CDs do it (though I can't speak for the details, I haven't used this method for a while - I am now using klibc instead of busybox and mounting aufs later).
If you need example scripts you could look at linux-live, for example. As to the active mounts, so long as you don't want to manipulate them afterwards, that seems to be no big problem.
