If you're talking about putting shorter cranks on, shorter cranks would require raising the saddle, not lowering it.

It just occurred to me that crank lengths of around 170 mm for adult bikes were settled on back when gear choices were extremely limited and and that they tended to be higher than the gear ranges people generally choose today. Riders needed all the help that they could get with those high gears, so they used crank arms that were at the extreme of what the average person could handle.

Now that there are no practical limits on gearing ranges on our bikes, it makes sense that people are finding that much shorter cranks can work better for them than cranks in the traditional length range.
