Yes I'm willing to compromise, but only to same degree. I mean for me hps are first a studio tool, this means I will not EQ them and then try to compensate for my dark mix.
You can EQ the HD-800 if you want, but this can cause a butterfly effect in the sound dynamics to some songs especially after today loudness war that most of the music is mastered minimum 6-to-9 dbs over just to fit the "industrial standards".
How about if you use one of those dummy heads that has a microphone in the ear-canal, and you then use that together with an EQ to make the actual perceived frequency response ruler flat? Couldn't that be interesting?
I suppose the opposite approach would be to master mainstream pop music on a pair of ATH50's or apple ear-buds since that's how 90% of people will be listening to music...
