Can't black holes also inhabit the gap by shrinking via Hawking radiation? Is that something we'd expect to occur given the current age of the universe or does it need longer timescales to occur? Also, do we know if there were special conditions during the initial phases of the post-big-bang early universe which might change the conditions under which black holes may form? For instance, non-stellar material condensing into a black hole?

Hawking radiation shrinks the black holes the faster the smaller they are. For microscopic black holes they evaporate in fractions of second, but a black hole the mass of our sun would evaporate in 10^67 years which is significantly more than the age of universe. So I think the chance to detect a big black hole that evaporated significant percent of its mass is zero.
