Not much, to all the questions.

The power will be limited by the low fall, and the flow of the Thames.

But OTOH the weir will be there anyway; the moving parts are easily
accessible for maintenance; and there will be no silting problems that
aren't already being dealt with by the Thames navigation authorities.

I'd say do it. It won't help much, but it'll help.
