Christ, Drew, are you nuts? A manifold spanning 4 tanks? Man, that would look like the brooklyn bridge! I mean a manifold like that could go at any minute. BANG! and you've had it, boy... Independent quadruples are the way to go. And hey, it's easy to manage your gas, I mean this is why you have 4 different types of tanks, you just get a different regulator for each tank. The problem with independent quads is that you can't rent the regs as most dive shops all use the same model. A definite safety hazard. Your best bet is to purchase used regs, this way it's easy to get a variety of easily distinguishable units. Paint each one a different color just to make sure. For low vis conditions, I also recommend tactile sensory inputs. By this I mean you want each reg to feel distinctly different. To do this you need to wrap one in barbed wire (the 100%, of course!), wrap another in beaver fur (oooo, baby!), the next one coat with vasoline (that slippery devil!), and the last one cover with silly putty (what fun during deco!).
