I don't think including the assets will be a good idea in this case.
It will change the mapsize and checksum, which will lead to a CRC error for all the ppl that allready have the map.
Just host the ain file on the servers that run this map and it'll be fine.
Renaming the file on the other hand will cause several other issues, you'd need to take care off then. (e.g. cubemaps, soundscape)
