To answer your question, yes there is a way. It involves acquiring someone else's saved game files. However, in doing so you then will be playing Ep5 under the conditions they achieved. (Did they save the Verdun? Leyte Gulf? Sink the Hakaga in ep4? etc)
Personally, I'd recommend you actually give Ep1-4 another go. But if someone wants to send you their saved games I guess go for it.
