Gordon: Bending the draw reeds on a chromatic will probably shorten their life a little, but what the heck? You will find that you can't bend them down more than about a semitone, though, because the windsavers stop the blow reed interacting with the bent draw reed in the same way as on a blues harp. Incidentally, you categorically *cannot* do overblows on a valved chromatic - the windsavers ensure that all the air goes to the blow reed. What happens in a successful overblow is that the blow reed is stunned, and the air escapes through the draw reed, which obligingly vibrates a semitone higher than the note it's tuned to.
The Tower is a different proposition again, because it only has one reed per hole (two actually, but you can only get at one at a time). This means that draw bending and blow bending are about the same as on a regular chromatic, and that overblows/draws aren't available, 'cos the reed you need just ain't there!
