Just a thought:
Could it work to create multiple layers of the equirectangular in a
photoshop file and adjust the colors individually for them, then blend
them with a feathered brush? You can work the edges either by working
on a double width twin set of the equirectangulars or by offsetting
them and repeat adjustments via a recorded action, again, on multiple
layers?
Or stitch a couple of panoramas, as you would for multiple exposures
with multiple color settings (from RAW) instead, and once again, blend
on layers?
You could then perhaps use a photoshop compatible panorama viewer
(without leaving photoshop and your work) to instantly check your
panorama through either of those approaches.
I am bringing this up, because, (not so much my mac, but) my pc often
has given me memory problems when extracting large views in photoshop,
having forced me to do it via the command line.
