if you want spokes to be the same length that not possible for the front but is for the rear. you need to use a novatec D772 or D792 hub in 32H drilling.
Using D772/771 and TL28 results in 293mm on rear spokes and 293.1/293.7mm on front. If you split the spokes to 293.4mm each it looks like you get a 1mm deflection/dishing of the rim. Could you get away with 292mm spokes on every side in that case?
