I don't want this to turn into a edition wars thread, please
What I would like to ask is how would you make the 3.x game feel more like 1E in play.
By this I don't mean, adding racial level limits or making up a new XP chart for each class.
By this I mean: What would you add or change mechanically or thematically with the rules to make 3.x graviate more towards the 1E/OD&D type feel (I know..I know..somewhat of an intangible, but humor me

)
e.g.
Might you alter the EL/CR/XP system? Change the power curve?
What feats would you add/delete/modify? (e.g. remove some of the more extravagant combat feats for fighters...nix or possibly modify item creation feats for Magic-Use...errr..Wizards..etc)
Modifications to some of the more classic/common spells?
Add/delete/modify some class abilities to certain classes? get rid of some classes period?
deletion of entire subsystems? Not someting like "skills", as the rogue would get hosed...but perhaps..and this is just an example...AoOs...or add in a different initiative system?
These are the type of things I'm interested in hearing from the ENworld community. I realize much of 1E's appeal was in Gygax's writing style..or the various original module writers. And that it was influenced heavily by the classic fantasy literary sources and did not have modern fantasy/sci-fantasy/sci-fi and anime styles influnces whatsoever. These types of things certainly had alot of impact. But I'm more interested in rules applications.
And yes I know about and own C&C. I'm asking specifically about changes to the current D&D rules system.
Thanks for your input!
