Been there, done that! Well worth doing. I'm just getting to the point of running out of drawer space. I dismantled and painted my rollcab a few years back, bought a cuboard/drawers rollcab and cut that down to just the drawers to make a topbox for the rollcab, and then bought a couple of side drawer units and managed to fit the whole lot together even though they are all different makes. The whole combo weighs over a third of a ton empty, I hate to think what it weighs with all the tools in it.
