I understand, but the consistency is broken anyway: C-u has an effect on 
yank, and no effect on isearch-yank-kill.  And mirroring the effect of C-u 
on yank (exchanging point and mark) in isearch-yank-kill is not possible.

I stand by my suggestion: using the universal argument on 
isearch-yank-kill to immediately enter the interactive selection of an 
element of the kill-ring with C-s C-u C-y without releasing the control 
modifier.

That's not correct.  C-s C-y M-y ... or C-s M-y M-y ... cycle through the 
kill-ring entries.  Typing C-u M-y enters an interactive selection of the 
kill-ring elements in the minibuffer.

What you probably meant is that C-s <something> C-y M-y ... or C-s 
<something> M-y M-y ... cycle through the kill-ring entries and appends 
each of them in turn to the <something>, and that typing C-u M-y discards 
the <something> and enters the interactive selection of a kill-ring 
element in the minibuffer.

It could indeed make sense to use C-u C-u M-y (for example) to enter an 
interactive selection of a kill-ring element prepended with the 
<something>, but I'm not convinced it would be very useful in practice.
