So what about simply leaving the bottom in the drawer, wetting the raw bottom

pressure out (slightly) as opposed to it being a single pressure point.

Thoughts?

It doesn't matter what technique you use to reverse (over correct) the bow/curve. If need be, try several techniques, see which one might work the best.

Again, as you bend it (slowly), listen for small/tiny cracking sounds. Bend the wood slowly (over a few hours, maybe), rewetting it periodically (if need be), if those small cracking sounds are heard. Old air dried cured wood will act like kiln dried wood.... sometimes difficult to rebend/reshape, with either wet or steam bending. In these difficult cases, you heard those small cracking sounds, as it's being bent/shaped.
