The 100-300 would be a useful safari lens - as would the equivalent mZuiko lens. If using either of them, I would consider the EVF to be essential too: using a long lens with the rear LCD would be less stable, more awkward, and likely to result in fewer sharp shots. I would not use a non-native lens on the EPL1 - handheld, it would be clumsy and bulky.
90mm and up the EVF helps a lot with hand holding.
By the way, take some decent binoculars too - it's too easy to get wrapped up in photography on safari and forget to put the camera down so you can simply watch and take it all in!
