Speed Force doesn't exist on Earth-16. Or at least, the Flashes don't draw their power from it.

But yeah, out of all the heroes, Barry is most likely to kick the bucket, speed force or otherwise. Robin grew up as Nightwing. Speedy as Arsenal, or Red Arrow. Kid Flash became Flash, because unlike his teammates, that title was open, and he inherited it. I don't think there's any other way to see mature Wally other than as Flash; a 21-year old is not going to call himself Kid Flash.
