It sounds like a recipe for disaster, at the most critical point in a dive,
the point at which you or your buddy are running out of gas, you will need
to fumble around w/ hoses to try and reconnect them. At some point during
the reconnection you will have no gas supply. I couldn't think of a worse
possible way to rig your back up.

Also, ask yourself do you really need a FFM.  As you can see even running a
back up starts to get convoluted. The FFM is a compromise unless you need it
for very specific types of diving.

In general I think FFM's are a bad idea, if you decide you need a FFM you
should really way the risks involved w/ a FFM.
