Short answer; no.
Why? Because bapt will become angry with you, because pkg(8)
won't be able to properly register the options, and people
will complain, and blame bapt. What's worse; dialog4ports(1)
won't be initialized, so people won't even be presented with
any options to choose from.
Long answer; *technically*, you could manage something. But the
effort would *far* outweigh any potential gain.

Sorry I didn't have better news, Yuri. :-(
