How significant is it that you identify AX.25 network addressing w/o 
TCP/IP equivalent?
How significant is the comparison of:
    TCP/IP SMTP only end-to-end
    AX.25 multi-hop mail delivery & bulletin delivery automation
How many hops between me and the global mailbox?

You have focused on the big mailbox in the sky.
The one that has the commercial brother [sailmail].
Do you envision a parallel development and maybe a commercial off-shoot 
as well?

I vaguely remember a 4yo conversation on IMAP & ham radio.
I better remember walking away from the encounter convinced overhead was 
a killer.
Because my IMAP happens at Internet speeds -- I have no real measure...

And I have tamed jnos to the point where my host delivers [pops] k8rra 
mail to me anywhere I happen to be on demand.
Doesn't matter TCP/AX incoming mail technology.
If the mailbox in the sky means another level of overhead to save a few 
address characters.. hhhmmm.
Not that I get a whole lot of mail from jnos...:-)
I haven't counted, but I think my unanswered mail count to Winnipeg is 
now three.

The TCP/IP network is robust with services -- DNS, ... HUGE-LIST.
The AX.25 network doesn't even have SSID standards.
Anything you code improves AX, then who gets on the bandwagon?
BTW: what ever happened to TCP/IP over the air experiment?

I agree with your premis -- hate typing [including mis-spelling 
addresses] -- do like some challenges.
An alternate to lots of address typing could be a simple address book 
incorporated into the BBS server?

If this lights your fire -- may the flame burn brightly without being 
your pyre.
Haven't seen much of you technical thinking on the subject.
Probably no need to see since you will do the coding.
You might however want to lay out the externals for a heads-up on how to 
apply your product in the field?.
