Hmm.  You have the same issue on the host, right?

For the guest we can easily filter out the key events.
For the host we can't.  This is the reason I picked a
key combination which has no side effects to switch
between host and guest.  And for the same reason I don't
think it is useful to allow the user to specify arbitrary
key combinations.

Which combination do you want use instead of leftshift + rightshift?
