Couldn't you just use binfmt_misc to match on #! and then run a process that can open up the script and figure out the required interpreter and arguments in userspace?

That should surely be possible for a distro that wants to do unusual things and only costs an extra exec() for starting up scripts which aren't known to be that fast anyway.
