In case of retry can the Diameter message have the same End-to-End identifier value as the original Diameter message initially sent.

Seems RFC 3588 doesn't clearly say about this particular scenario

It does say. One example from the RFC(section 5.5.4):

It is important to note that multiple identical requests or answers MAY be received as a result of a failover. The End-to-End Identifier field in the Diameter header along with the Origin-Host AVP MUST be used to identify duplicate messages.
