I don't think this is necessary, and I'm not even sure such an
application will be accepted.

The current trend for protocols that operate with both plain-text
and encrypted traffic is to start with an un-encrypted connection, and
then use a "STARTTLS" command to turn on encryption. The two sides can
then negotiate if they can/will communicate.

Since this appears to be the method preferred by the Internet
authorities, that's the one I've though about implementing. That
shouldn't stop you from using stunnel, though.
If hb encryption via stunnel is implemented then a port for plaintext redirection is needed. thus the idea of requesting non-taken port( from iana) for hobbit encrypted message.
For my understanding, BB Pro can do message encryption already and looks like they 
are using port 1984 also.
What is the impact of mixing bb encrypted message and hb encrypted message protocols on same port number ? and I don't believe Quest publish the bb message encryption protocol. 

I think getting a port for hobbit itself is still  good in the long run.

It's handled by IANA, You request it through
http://www.iana.org/cgi-bin/usr-port-number.pl
