Aqueducts not bound to tiles next to City Centres

[thecraftybee]

Are there any mods out there that remove the restriction that Aqueducts must be adjacent to City Centres? I would sometimes like to build Aqueducts in the second or third ring, especially if my city has not been founded on fresh water.

IIRC, Quo's Combined Tweaks changed Rome's Bath to be unrestricted, but I can't seem to find any standalone mods for the basic Aqueduct. Would this be an art issue rather than a technical one?
