Well, maybe this is OK for playground, but our dome must rotate as well. So there is no support on the lower part.
Also, cut needed for astro-dome is longer (zenith!)
My point is (probably 2c worth or even less), that it may prove to be more expensive to try and adapt the watertank, than building something more suitable from the scratch.
