It's hard, but not impossible. Actually, the parallel design increases the overall flow.
The problem is that the valves would have to be set to seperate the flow in such a way as to get a specific ratio. It's a problem because you can achieve the same ratio wether the valves are all mostly closed, or all mostly open.
Ideally, you'd leave the CPU loop open, no valve, then put a valve on the GPU and Chipset cooler loops. The more open these valves are, the better overall flow, but less flow to the CPU.
Running the WB in series is far simpler, because there's no adjustment, but then, there isn't as much flow.
The ideal setup would probably be either:
1- a parallel loop, with the GPU and chipset valves barely open
or
2- use T fittings, where the CPU feed flows in a straight line through the T. (as you propose)
1-This would divert most of the pumps flow through the CPU only, with a little bit of relief from the other two loops. You'd achieve near max flow rate through the CPU block. (where max is one loop through the CPU wb only)
2-You'd achieve a similar result as #1, but more flow would be diverted to the other 2 WB than you probably want.
What it comes down to, in terms of flow dynamics, is how each block resists flow. Usually, the CPU block is (by far) the most resistive, as GPU and chipset coolers are often simple open block designs (i.e. no channels), and as such, have very little restriction. The purpose of the valves is to correct or compensate for those flow restrictions in such a way as to divert more flow to the CPU block.
I hope this helps... In short, I'd go with the valves on the GPU and chipset cooler loops. You'd have to monitor the temps, to make sure that you achieve the cooling that you want for those 2 WBs.
