I learned not to do that when I gigged a lot in my college band days. When your principal band gig is being the organ player, and you're schlepping around a Hammond, an amp, and associated connector cables it's just too much to also have to untangle a bag o'cables. You're beat from just dragging in the organ. The drummer and I were always the last ones to load out. He had his drums, cases, stands, cymbals, and I had that damned Hammond, the amp, and my volume pedal, cables and even some effects.
For a while I even played a Key Bass in the band, a la The Doors, that would sit on top of my organ...and it had to have its own amp, too. Sweaty stuff, being a keyboard player back in the day...
