To both questions you raise above: C-y and M-y in the minibuffer are the same as
they are in any buffer: C-y yanks the last kill and M-y replaces the text just
yanked with a previous kill.

I was thinking that only one C-u would be needed to then let C-y do what it does
now.  IOW, C-u C-y C-y... to repeat.

But I suspect that proposing C-u for this is a non-starter.  I expect that there
will be significant attachment to the use of C-u to both exit isearch and be
passed along to the following command/key as prefix arg.

OK by me.  I completely forgot about such scrolling.
