CBS' Supergirl and CW's The Flash Possible Crossover?

This could be possible since both shows are set during the same time period, both shows are produced by WB Television and DC, and The CW is co-owned by CBS and Warner Brothers. Both lead characters are likable by fans as are Grant Gustin(The Flash) and Melissa Benoist(Supergirl). Then there is the Glee reunion factor between Gustin and Benoist which would probably get the Glee fans interested. Pretty much a win-win situation for all involved. Anyway, that's about it for now. Til next time, have a good one and behave yourselves, true believers.
