You can pass a string command to maya.utils.executeDeferred like this:
maya.utils.executeDeferred("allIWantToDoIsBuildAMenu('FFS')")
I guess that will run your code when Maya finally goes idle or something.
There may also be some trickery you can do that will force Maya to
evaluate the main menu early.
Just don't try to parent a menu to 'renderView' because apparently that
never exists, and when it does, it's volatile. So maybe you could do it
with some kind of callback... I think maybe it's the same for other
volatile windows, but I haven't really tried.

Apparently there's a callback specifically for adding render passes to the
render view menu, but not for adding menu items to it in general? Very
odd. The Maya callbacks kind of seem like a random assortment of hooks
asked for by various studios at various times.
Best of luck!
