A tiny ray of hope for you. The LDS microfilmed nearly all extant parish rcds beginning in the 1940s. The National Archives of Ireland did the same, only I don't know when. I think this occurred after the LDS effort.
I have found cases where the LDS rcds contained earlier rcds than those available online, and perhaps the NAI as well. The LDS rcds are available through its Family History Libraries for a small fee. In some cases, LDS members will have added geneolgical info from rcds no longer available, or held by private sources.
Give it a try. Pls let me know how it goes. I haven't used the LDS services myself.
