No it wouldn't.

Considering how magic works in Edolas, it is extremely unlikely that Demons were created there, so it is very unlikely that there ever was a Edolas Deliora in the first place.

Furthermore the pasts of both Gray and Silver/Deliora match up. Even if there was an Edolas Deliora to begin with, it's unlikely that it would have had the same experience as the Earthland Deliora.
