Turning a Dark Elf good?

[Picked]

Have a dark elf. I am considering some faction grinding. I would like to be able to run around good cities and not be kos everywhere. I'm sure this would be a huge undertaking, but I am curious what all I will need to do?

Is it worth it? Or should i just bow to social pressure and be a bad darky. I can get good faction in Faydwer by killing orcs in crushbone. And orcs in the commonlands will get me faction with freeport. I realize this doesn't get me faction with the bankers.

What kind of process am I looking at here? I have looked at opposing factions and I see quests I can do to get that faction with merchants and such up to snuff.

Does anyone bother with this when they play characters? I see ogres, iksars, and other races running around places like CB all the time.
