Fleet, we appreciate you taking the time to put this together and help consolidate our community content and get it working with v5.0. However, getting a map up and running with the latest build of the game should ultimately be the responsibility of the map's author; I'm currently wrapping up a new revision of Chateau DuClare and will release it soon.
When updating a map, it's more than simply packing in the missing content. The author might want to update certain assets, tweak the layout, adjust playability, etc. A map is an author's vision; it becomes undermined when old revisions are brought back into circulation. If an author chooses to update and release their map, that is their business.
It's also worth noting there are soundscape files, music script files and loading screens all linked to the BSP. By adding the _fix suffix to the maps, these links are broken. I hate to lecture, but quality control must be exercised when re-releasing third-party maps; there are many steps involved and plenty of room for things to go awry.
Also, there are a handful of maps in that archive that didn't need fixing since they were released after v5.0 came out: ge_osiris_a2, ge_hokona_a1, quake_e1m7 and ut_codex_v2
Again, thank you for taking the time and effort to do all of this, but next time at least ask the authors before you go through with it.
