It may be possible, but would likely be quite a mess.  Ordinarily you 
would develop your changes on a single instance and get them reviewed 
and merged before applying to other instances.

If there's a complicated reason why that won't work (for example, you 
need to test them on multiple nodes before you regard them as correct 
enough to merge) then here's the hacky method I would recommend:

1)  Install puppetmaster::self on all nodes
2)  Commit your in-testing patch to gerrit, but mark it as a 'work in 
progress' in review so that reviewers know to ignore it
3)  Use the cherry-pick gizmo in gerrit to cherry-pick the patch onto 
other nodes
4)  test
5)  go to step 2

I use that process pretty frequently; it's not as big of a pain as it 
sounds.  Ryan can probably set you up with a spiffy one-step salt 
command to perform step 3 on many nodes at once.  I don't know the 
syntax for this offhand.
