Thoughts?

It would be far more efficient to attach thrusters to the
object being winched and move it to that location - or, if
that is not possible, attach the tether line (which you've
got on your object being moved) to a tow ship.

Assuming that the object being winched is not itself
generating thrust in the opposite direction or is not
being affected by gravity, even a small 'tug' can move a
large ship (it just will have a maximum that it can apply
to meters-per-second).

BUT: what you're talking about is doable.  Just not very
practical.
