No, to verify something you have to show that it can be done. Speculation about a possible evolutionary path from TTSS to flagellum doesn't show that it can be done.
If the TTSS actually did evolve into the flagellum the Theory of Evolution would pretty much have to be thrown out the window. . .Curiously, nobody in evolutionary biology agrees with you.
What would it mean if the TTSS preceded the flagellum?

Really? Which of the steps described is counter to physical possibility?
> What would it mean if the TTSS preceded the flagellum?
That the TTSS existed first, at least for that particular bacterium. Not exactly something that would shake the pillers of science.
