A combination of what TSandM and danvolker suggested.
Small 3' SMB with finger spool in left thigh pocket and biga$$ SMB in the storage pouch of the backplate pad.
The small SMB is for team drills and can easily be restowed in the water. The large SMB is for "lost at sea" scenario or can serve as a backup buoyancy device. The strap of the big SMB is clipped to the butt D-ring and does not have its own spool.
PS: After the recent incidents where boats left divers in the water I waterproofed three flare launchers and keep them in the right thigh pocket on boat dives. I used these and made O-ring sealed delrin plugs for the muzzle end. The other end is already tightly sealed with a screw-on cap.
How exactly do you waterproof these? I am very interested in your idea here. I cant decide if its completely safe, but I am still interested.
