Using cnc mill as a powered hacksaw?

This weekend, while thinking about how much effort it is going to be
to cut off about 2 dozen pieces of 1 inch square brass without a power
bandsaw, it occurred to me that maybe I could use my cnc mill as a
poor-man's powered hacksaw. However, instead of having the blade move
back and forth, I would mount my material in the vice on the mill
table, fix the hacksaw frame to the base so it can pivot up and down
with a small weight on the top of the frame, and just set up a bunch
of back and forth g-code on one axis to move the material and table
under the blade.

Anyone ever tried that?

Reasons it would not work?
