Well like i said before on other Arrowverse message boards on and off this wiki, Godspeed shouldn't be introduced this season, not even the next one. Not until they develop the character further on Flash: Rebirth. With minimal lore, you don't have much to work with. Inertia however would make an excellent foe for Wally or Impulse if he is introduced.

A villain i would like to see done on this show that we have never seen, but have in the comics is Zum. Considering aliens have been introduced on Earth One, this alien speedster would be a cool foe to introduce. Though a villain introduced as part of a crossover would be someone i want more. That villain is the Riddler as a crossover with the FOX show Gotham. As in the New 52, The Riddler tried to frame the Flash in a one-off story they could adapt. The Riddler on Gotham is the perfect fit for that kind of story.
