The reason I asked is because I think there would be a benefit. Whether it was from a wider channel, or a taller channel it would be the same effect. My reasoning is pretty simple, you create significant, unnecessary pressure drop by having the cross-sectional area of the block significantly less than that of the barbs.
It seems to me that you would get much better flow rates with the larger channel. And, as this is laminar flow, it seems equivalent to some of the maze/spiral design blocks (i.e. laminar flow etc). Those blocks, looking at BillA's testing (specifically the GeminiCool Tsunami), benefit much from increased flow rate.
One indication that it may be useful is that D-Tek, Danger Den, etcetera have all designed their blocks with the channel cross-section at least as

I think this is entirely wrong. All of the waterblocks tested by BillA benefit to some degree from increased flow rate, but the amount of benefit varies greatly between blocks. It may well be that your extroardinarily "tight" block creates such pressure drop that both of your current blocks are performing well below where they could, and that differences would begin to appear if you redid them either taller or wider. I think those components could in fact be minimizing the differences by slightly compromising the blocks functioning.
Also, I think one of the arguments for a thicker base (I know, I'm beating a dead horse) is that with other laminar flow blocks, the manufacturers use thicker bases. Another argument is that some of the makers here have tested their blocks, keeping everything the same but reducing the thickness of the base and found that there is an ideal point, and it's not necessarily as thin as possible.
Anyway, hope this wasn't offensive, I do that sometimes. I'm impressed regardless, I just think you can get a better block without too much work.
