The real intent of my questioning is to provide
a counterpoise system whereas the tuner does
not just have an unbalance by simply feeding
the random wire, but a balance achieved
whereby the counterpoise connected to the
tuner acts as the other (missing) half of the
unbalanced system, thereby balancing it just
as the ground image does with a quarter wave
antenna. Does this make sense?

Yes and perhaps I have a workable idea to get there.

First, an assumption: Your long wire out the window frame has only a short
run to the tuner. That is, the tuner is on the same wall as the window
frame and is near the window. How'm I doing so far?

Along that same wall, stretch out a heavy piece of straight wire -- can be
insulated but you'll cut through the insulation as needed -- from corner to
corner. It's like a workbench ground bus but it's not grounded, per se.

Attach the tuner ground to it.

Buy two (maybe more) locking metal tape rules. Craftsman, Lever-lock. At
the zero ends, securely bolt or clamp the metal tape rules to the ends of
the heavy wire in each corner. Yes, you're ruining the tape rules by
mutilating the ends but we know you're desperate. Courage, man!

Stretch out the tape rules until their lengths become whatever you need for
a workable counterpoise, recalling that HF antenna elements (and
counterpoises) do not need to run in perfect straight lines. Zig-zagging is
your friend in a confined space. Even go up the wall(s) in the far corners.

This method, if it works, has a bonus. Once the lengths are established for
each band, the exact lengths can be eyeballed directly off the tape rules
and noted. Alternatively, just scrawl band numbers on the walls. (Hi-hi)
