Nah I don't think its a good idea. The epic reputation feat covers a wide arrange of skills that one who has worked towards getting noticed should get, not every epic character does this. Ta'karsh is a gruff cloistered individual, his focus is to not to get known but to forge wonders for Dorand. But in like Remiel's epic his name became known across the land as Toran's Justicar, so he would have roleplaying reasons to take the feat. On the same token, Reggub is known by very few and are mostly old players, and even fewer know what happened in his epic or who he answers to now.
