Ionospheric effects account for about half the DOP, IIRC. So, if I understand your requirement, and you are interested only in the relative difference of position between two nearby units, you should obtain a relative precision about double of the absolute precision of a single unit. If the units make use of WAAS or EGNOS, probably the gain in relative precision would be less, I think. If you do a test, let us know your findings.
