GDB is feature-complete for such "independent session".

If there is a problem implementing it to Eclipse you can just create
a "tee"-like intermediate server:

Eclipse <-MI-> new-server <-MI-> gdb
|
console <-MI-or-CLI-+
|
console <-MI-or-CLI-/

the point is every command sent by new-server -MI-> gdb should finish
immediately due to async/non-stop so any command from "console" can be sent by
new-server -MI-> gdb without any delay.

[ You should have more experience with async/non-stop/MI than me, though. ]

This happens even with current Eclipse GDB Console, for example by modifying
a variable displayed in the Variables window.

TBH isn't a VNC session to the full Eclipse GUI more suitable?
