Can you produce any evidence whatsoever that this could be worth the cost?
Aside from the nontrivial development effort needed, there would be
runtime inefficiencies created --- for instance, inefficient use of
buffer pool storage because it'd no longer be true that any buffer could
hold any block. Without some pretty compelling evidence, I wouldn't
even waste any time thinking about it ...
