There are two sets of gears in this trans. The ones you can shift and the final drive gears in the differential.

Well, the thrust vs. speed curves get stretched out and no longer overlap if you make the final drive taller, so actually I think the rpm drops will be less if you make the final drive shorter, in effect giving you closer ratios.
