I wonder. *Strokes Beard*

I thought it would be amusing. But I can change that if you want.

EDIT:
[quote=@Lord Wraith]Furthermore they have already said there will be no cross overs in the first season, but as Supergirl acknowledges that Superman is in fact out there, it makes me wonder what that will mean for the CWverse if Supergirl does indeed cross over with Flash or Arrow.

As far as I know from my research on the subject (I <3 Fash-Arrow crossovers) is that Supergirl will not be having crossovers with Flash or Arrow. Which is why they wanted it on a separate station.
