Cool idea but I wonder really how much cable is inside that spool. I can't
imagine much more than say 3 floors... 4 tops.

Since the tension force, T, is in the same direction as the displacement, h, we
know that the work done is equal to hT.
We know that the sum of forces acting on m is T – mg which is equal to ma.
Therefore, T = m(g – a).

It would work fine at most any length, just put the wire in the wall unit, not
in the hand unit.
