I'm not sure how you think this is fare. Unless you have a high opinion of the Avenger's lined up. Which I don't think you do.
Hector might be the most powerful Doctor Fate. Throwing in Corrigan Spectre is too much. Not when Doctor Strange is so weakened and the Sentry is so inconsistent. Make it the Void, Classic Doctor Strange, and Hal Jordan Spectre perhaps.
Throw in Doctor Voodoo for Nova Prime or maybe someone else on that level like Morg.
Kent might have more "feats" but I always felt that Hector was intended to surpass him. One thing that stood out to me was that he had moved beyond being a physical being. That's what I remember from reading his appearances. I think he was watered down down the line.
The Thunderbolt is a 5D Prince, not a 5D Imp. Similar, but different and not as strong.
Dr. Fate (Kent Nelson) was able to stalemate the Thunderbolt going all out once (both going all-out that is), so the T-bolt is 'merely' around Lord of Order level or so.
