Is my SMALL plasma table idea nuts?

Since I have limited space I am considering making a small plasma
table that sits ON the metal sheet to be cut. I already have a small
cutting table and ventilation system for my Powermax 600 and thought a
small (maybe 2' X 3') table might be fine for my art. If I wanted to
cut larger pieces I would cut the graphic into pieces in the cad
program, make piece-meal g-code and move the table around the sheet of
metal. Since it would be small the alignment issues and cost would be
reduced significantly too.

Is this idea nuts?
