Do particles in this model re-adjust their spacing to the new space being created?

e.g. after 10^18 seconds, would the diameter of a hydrogen atom still be the same? or is it scaled to be huge (relative to now) ?

Space is growing, not the matter within it. The diameter of a hydrogen atom is dominated by the fundamental forces, and the expansion of space is insufficient to overcome this force.

so shouldn’t this fine-scale readjustment of the electron/proton distance be measurable?

Maybe this is the ‘wind’ preventing the electron from reaching the nucleus :)
