Delete please..
Well the first repo, if I'm not mistaken already has Eluna installed. It's mostly meant for straight merge into mainstream TrinityCore.
We don't do delete "handouts". Matter of fact, when you deleted your post content you broke a specific rule.
Section: 1D, Rule#24
Do not edit your support posts if you are going to delete all of its contents, code, or usable data that can be useful for someone else. This screws with SEO and potentially ruins members & guests experience when trying to solve the same issue for themselves. This will result in one warning and afterwards, a ban. NO EXCEPTIONS.
Do not delete your support post content as it is still beneficial to others.
Yes, ElunaTrinityCoreWotLK already has Eluna installed. The best thing he can do is use up-to-date sources. Any custom edits (if any) he did to his own source can be moved to the new one with ease. Using any earlier revision of Eluna isn't recommended either, if that's what he wanted. (Don't know since he deleted his post content...)
