I've no doubt you can get 32H open pros to hold true, but it's also the case that you're more likely to get fatigue problems if you're a heavier rider with that combo than either a 36H or a cxp33 32/36H. It's worth being aware of - if you're not fussed about weight, then the extra cost is negligible and you'll end up with a stronger wheel.
If you're not fussed about weight, run 4x 48h.
