Not bad. You only missed a few. Graham Hill was another Indy winner.
The others you missed were Bill Vukovich, Tony Ruttman, Pat Flaherty, Sam Hanks, Jimmy Bryan , Roger Ward and Jim Rathman. It was kind of a trick question. The last drivers named were Indy winners when Indy counted for the world championship, so they won in both categories.
I should have gotten Graham Hill. Darn it!
As for the others... well played, sir. Well played.

No Starter, they won in the WC round run for Indycars but not F1 which was a different spec! So back to your original question it should be 'also won a round of the WDC' not a win in F1 (#pedantic smartarse)
Well with PS rules in place, and with same spec being noted; I'm gonna throw in Jimmy Murphy w/his Duesenberg.
- 1921 French GP
- 1922 Indianapolis 500
Same car, same specs. Hope that works. Yeah I know... still not F1
Those of "questionable knowledge" will be the scientists. You might think that rocket science is hard but:
