There are probably other ways of reintroducing Goblin as the main villain. The Clone Saga - as infamous as it was - had Goblin as the main villain and he didn't even physically interact with the cast for most if not all of it.

Have him in a "the man behind the man" position where he controls things, or maybe don't even reintroduce Goblin as the main villain but Norman Osborn. Norman Osborn (depending on if the world knows he's the Green Goblin at that point) could run for mayor, and he'd have a ton of power.
