It is more reasonable to postulate that the primordial black hole solar system gains mass (especially the heavy elements) as the universe just begins its expansion. First, the PBHs would form, then heavy elements and finally the lighter elements, especially hydrogen. It is hard to see how the PBHs could acquire matter just after forming. However, there will be a point during the expansion of the universe when the PBH solar system is floating in a sea of condensing matter. If the PBHs acquired mantels of heavier elements just after the beginning of the universe, prototype solar systems would form with planets much the size observed today. Suns, made of heavy elements, would radiate by gravitational contraction for millions of years. Then they would cool, forming large astronomical bodies of dark matter, not observable by the astronomer's telescope. While the heavy elements form first, both they and the clouds of hydrogen and helium gas form at approximately the same time. But the heavy element solar systems aand the clouds of hydrogen and helium gas may not get together until much later.
Prototype solar systems can add significantly to the estimated mass of the universe. These prototype solar systems can drift through the universe for billions of years before being attracted to the gravitational potential of a huge cloud of hydrogen. Then, the dark stars begin to acquire substantial hydrogen mass. The cloud need not have specific angular momentum or be disc shaped, but may appear like most of the gaseous nebula usually observed (e.g. the Orion nebula).
