I would have prefered Richard Fisk. It was one of the ideas that came to the mind of Tom DeFalco.
It never came to fruition in the comic book, Richard Fisk being revealed as the Rose instead (after Tom DeFalco left the book).
I think that Richard Fisk being Hobgoblin would have been an awesome idea.
Since the Schemer story (his first appearance), it has been proven that Richard has combat skills and he knows how to use (& perhaps even build) high-tech weapons & vehicles.
I can see Richard combining the Green Goblin costume & gadgets with the cloak & weapons of the Schemer to make the Hobgoblin's armory.
I can also see Richard being worried that her mother might learn the truth about him.
I didn't like Ned Leeds as the Hobgoblin (too crazy, too unstable and it ruined Leeds' reputation as a nice guy which he had earned since the Silver Age).
Roger Stern probably had from the start the idea that Kingsley was the Hobgoblin. Roger Stern is an excellent writer but, in this case, he used one of the oldest threadbare tricks in fiction : two brothers, one impersonating the other when it is needed. Also, contrary to Fisk & Leeds, Kingsley was a recent character and almost a stranger to the reader.
So, well, Kingsley is cool but I would have prefered Richard Fisk.
It would have been interesting if the new villain was revealed as the heir of two legacies of evil (the Osborns & the Fisks).
Richard Fisk could have become the reverse of Peter Parker ... A Byronic character, an Anakin Skywalker falling from grace ...
Unfortunately, in 2017, it is probably far too late for that ...
Many years later after the Hobgoblin story, Richard was killed by his own mother. Still, I speculate that Vanessa might have actually killed Alfredo Morelli instead of Richard because the true Fisk Jr had already entered the Witness Protection Program just after he had been arrested as the Blood Rose.
Nevertheless, even if my speculation is correct, it is far from certain that the "true" Richard Fisk might ever come back from the dead.
This secondary character created by Stan Lee & John Romita Senior will probably stay in comics limbo a very long time.
