No, there's no point using FE to display the EML on the server, since there won't be anyone there to see it.
You don't need to "display" HTML at all - that's what browsers do - so what you'll want to do is split the EML into it's fundamental parts, then push the parts into a group, or file, or whatever, and then just make a form with those fields. The Html part of the email can be sent "as is" - just make sure the field is set on the form to "allow html".
