Jones is not the HW GOAT, he is LHW GOAT, and considerd the all time GOAT. Mind you that all of this fighter GOAT and greatness talk is subjective. I agree that Aspinall can surpass jones as HW champion, as jones has one title defense and not much more than that. I do not see him surpasing GSP, Jones, Silva, DJ and so on as reigning divisional champions as the his division lacks divisional elites.
Jones has no legacy at HW, he is just there to pick up a check and cash out. His legacy is behind him at LHW and so is his prime. If Aspinall can beat Gane, and defend his title more than three times, I would give him his due. Yes, Aspinall does not need jones to forge his legacy at HW but it would help as his division lacks legit elites, legacy and prestige in its fighters. .
