Hi modest,
The redshift / expansion relationship remains intact in the scenario (larger recession velocity = larger redshift). Metric expansion redshift is due to the recession velocity of the body the photon is moving towards.
In the scenario proposed, expansion redshifts are not eliminated (they remain the same). However, the wavelengths of the photons (and/or particles) are smaller in proportion to the size of space itself (more space + same wavelength photon = photon has smaller wavelength to space size ratio).

Photon wavelength increases with the expansion of space while the size of atoms do not.

To be clear, a photon's wavelength does not actually change in transit, rather it is the recession velocity of the observer that redshifts the photon.
