I have been using independants for some time. It is possible to get at the
pillar valves to turn them off or on whilst underwater, and with a drysuit.
It takes a bit of practice and requires the cylinders to be mounted at the
correct height, then you might have to "walk" your hand down the hoses until
you get to the pillar valve.
Blocks are available over here. The use of them is safe if they are used
properly (like most things). Mine is chest mounted and has two outputs
and three inputs. Each input has an on/off switch and two of the inputs are
connected to my main cylinders via large bore, quick disconnect, drysuit type,
connectors. The third input is for travel and deco mix: On the way down, it
is connected to my travel mix and I swap one of the main cylinder's connecter
for my deco mix connecter on the way up at the stop before I want to use it.
My deco cylinder(s) are pressurised and turned off; they are mounted upside
down next to and infront of the mains.

The pillar valves of the deco cylinders do not protrude below the base of
the mains.
One of the two outputs is connected directly to a full face mask and the other
goes to a 7ft hose via another valveand quick disconnect. On the far end of
this hose is yet another quick disconnect with a second stage on it or the
second stage can be removed and the hose will plug into another simmilar
mixing block to cope with a buddy's problem.
All the quick disconnects on the hoses are clipped to D-rings with shock-cord
so that I don't "loose" them.
