Well, y're half-right.  You have to keep the 64 byte packets,
but you can have more than 3 windows.  (7 is typically a 'good' 
number.)  There is, at this point, no way to fix the packet size
handshake.  (But why would you want to create a new 'g' protocol?
You might impliment a cleaner version, but a 'new g'?

Hardwired constants and fixed size buffers have nothing to do with it.
The handshake code is broken, always has been.  No way to fix it now.

What we really need, is a good 'SLIP' modem, and dial-up slip service.
Then we could use SMTP, and NNTP, and do away with uucp, (for the most
part.)
