Well first off those are great pups but alot of people like the tone of the wood and the body of Gibson LP's more than the electronics. Most Gibson LP's have a mahogany body and neck, a rosewood fingerboard with a set neck instead of a bolt on type. The flamed maple tops and bottoms don't affect the tone that much. So if your guitar is built like above then you can get the classic LP tone out of it with almost any pups. If it's not then you are dealing in futility. You probably will get a good sound out of the Epi but it wont be quite as crisp and have the same kind of sustain a real Gibson will have, regardless of the type of pickup you put in it.
