That's just RSS. Most of that is Gtk libraries and their dependencies
shared with all the other applications on the device. VmData & VmStk
values from /proc/<IM PID>/status file give a slightly more accurate
value of what RAM is private to input method.
It's still a lot, but not even near 6Mb...

Xrestop reports 314KB of Pixmaps for the input method, but once I
close it, only 96KB remains. I think that is the Gtk scratchbuffer
(i.e. reserved by Gtk, not input method) as I can see it also in
/proc/sysvipc/shm file.

I don't think you need to do the Gtk IM-module, I think the IM module
communicates with the keyboard using X messages (i.e. your X11 expertise
will actually help :-)).
The target input method window seems to be told here:
# xprop -root|grep HILDON
_HILDON_IM_WINDOW(WINDOW): window id # 0xc00003

See into: /etc/osso-af-init/keyboard.sh
It's started with a watchdog.
