Actually, thinking more about it, I wonder what's wrong with just doing 

    emacs -l '$PWD/foo'

or even

    emacs -l $PWD/foo

    
So then it's just a question of whether it's worth saving a few
characters on the command line (to write ./foo instead of '$PWD/foo'),
to which I'm inclined to answer "no", especially since implementing it
turns out to be rather fiddly.
