I doubt it would be that hard to make one, and that would give you the advantage that you could have it fit exactly, with pockets where you want them etc.
You could specify what material you wanted (see if someone has an old boat cover that's knackered perhaps) and with a little planning and an industrial sewing machine you could sew a pouch, with maybe some elastic in the front to hold it closed. Then bolt it to the console with some big washers, and bob's your uncle.
Just don't tell my mother I know how to use a sewing machine!
