What about the following UI?

M-y triggers a kind of kill-ring browsing: it opens a small buffer above
the minibuffer with the next killed text (that which would be inserted
by C-y), accessible with M-y or M-n. If the user presses M-y or M-n, the
buffer expands to display the previous killed text as well, accessible
with M-p. In any event, pressing RET inserts the current killed text to
the buffer, and pressing anything other than RET/M-y/M-n/M-p kills the
buffer and resumes normal editing.

C-y M-y directly jumps to the second step of the above, but inserts
automatically the current killed text, preserving backwards
compatibility.

Therefore, C-y M-y M-y ... does the right thing, with the added
convenience of a buffer allowing you to go back to a previous
completion. Also M-y becomes a nice alias for viewing the kill-ring.

This has the merit of not binding M-n / M-p in anything else than the
mode this buffer would be displayed in. Doing it any other way would
probably cause confusion to users/modes who bind M-n/M-p.

The appearance of the small window would be controllable with a boolean
setting.
