People were asking me the same thing about my low C# string over 10 years ago and then a few years later a few companies started offering low C# strings.
There will always be opponents to things outside of the standard. If there are no pushes away from what is "traditional" or "standard", there is zero possibility of innovation.
Period. The electric bass was a innovated push from the traditional instrument, the 5 string, the 6 string, contrabass, so on, so forth. Whether or not it's practical or "useful" (for whatever that term is worth), we need movement like this just for the sake of keeping stagnation in check.
That being said, how do you go about tuning your Contrabass accurately? When I tried F#, I had trouble with tuning and that's not quite close to where you are.
