Will there be a Smallville spin off TV Series now that Smallville is finished?

Because they can't just end a great series like Smallville when
there is so many more story's to be told. And I would love it if
they had a spin off series and called it Superman or Metropolis. Or
even the Justice League as so many Justice League characters have
appeared in Smallville.

I would even like to see a ligeon of super heroes TV series as well as
characters have appeared from that in Smallville as well. But maybe
not just yet as there are loads of things they could do before then.
