You could buy the 36h wheels AND lace up the old 32s as incentive to shed some weight

Speaking of weight, The two rim choices are slightly apples to oranges. The Open Pro is a box section and a little over 400g per rim; the Deep V is semi-aero and almost 600g per rim. Total, you're looking at almost a pound in rim weight alone, plus possible cross section/wind issues. I'm not necessarily pointing to one or the other, just pointing it out.

Anecdotally, I attempted to use a set of open pro rims for commuting duty (<200lbs of rider, plus lightly loaded panniers) and broke my rear wheel at the seam on rough pavement after 6 months or so.
