I submitted the -iad question to Elfling and a very obvious point that we'd missed was made: the changes from Gwareth to Gwared and Echoriath to Echoriad cannot imply a change from Doriath to Doriad, because _Doriath_ appears in "The Wanderings of Hurin" alongside _Echoriad_. This is, then, not a universal change from final "th" to "d". I suppose it must merely be two independent changes to the specific names "Echoriath" and "Gwareth".
In light of this, I think we probably should use "Echoriad" and "Gwared".
