How long would a minimum sized black hole last? Since the temperature of a black hole is an inverse relation to its size then a black hole with a schwarzchild radius that small should have a very high temperature. The super massive black holes have extremely low temperatures and extremely long lifetimes, so I would expect super small ones to have very short lifetimes.

Also of course there is the question of what the Planck length means. Ethan Siegel discusses this in his blog. The Smallest Possible Scale in the Universe. I don't expect that makes much difference to what you have to say, but it is an interesting discussion.
