from your description, I can see that you are having an use case that should
be supported. The next steps would be to
a) write it down, open up a ticket on bugs.gnupg.org
b) come up with a good proposal how to technically solve this
c) come up with someone doing or funding the work.
A workaround in your case could be to use two readers, one for each token.
I'm no expert, but reading up a bit, it seems that shared access from several
application could be a problem, either because of the state of the token
that needs to be handed over and otherwise because of speed issues if
applications have to reset the token to some clean state. So I'm unsure if
a "non-exclusive mode" is technically feasable.
