Your approach is what is needed. And another thought is to cut rather than add. Ex the HE6. Great headphone with a bloated bottom end. Cutting it at 140 db and below about 4 or 5 db makes them have more bass detail and more staging as the upper and mids become more apparent. The same with the LCD 3 except they also need a boost above as well.
A long time ago I had a set of Allison acoustic speakers . And they could be adjusted with some sw,s in the back. I ended up calling them for tech support . The owner answered the phone, his words remain in my head to this day. He simply said make them sound how you like , not what someone tells you. He also said wpuld you buy a preamp without and freq controls like bass, mid and treble. The point is we all want to think our system is pure and not needing and adjustments.
I have always used EQ from then on. I do not use it all the time with all headphones . As the stax009. I may add a little bass. Or the hd800 given the genre I might cutt the highs back a little.
