CAMCO makes an adapter that does just this (joining neutrals and ground) - with the warning that it won't work on a GFCI outlet... The 20A pedestal outlet in a CG should ALWAYS be GFCI protected, which makes this adapter (or equivalent setup) relatively useless...

The GFCI would see imbalances and trip pretty quickly I'd expect.
