I just now thought of this. What if Adam's whole "poison paint" thing had worked, and Jeff wound up dying? I mean... would that been such a bad thing? Fallon certainly didn't need Jeff, she was interesting on her own. Not even any of the other characters really needed Jeff around. Sure, Blake wound up loving Jeff more than his own sons, but perhaps it would have been a good thing for Jeff to be gone by Season 3; it'd force Blake to bond with Adam and Steven. As for Alexis, she was going to become Empress of Denver anyway, so she wouldn't have needed Jeff to be around to help her run things. Even Adam didn't really need Jeff (although I did like their rivalry) since it would just mean he'd have more fights with Steven and Fallon. Heck, Jeff's death could have even benefited Kirby of all characters: she'd no longer be mooning over him, and she'd get to start a passionate-yet-twisted romance with Bad Boy Adam! Perhaps she discovers that it was Adam who poisoned Jeff, but she helps cover his tracks. Even future characters like Amanda could have benefited, because once the other Colbys showed up, we could have gotten a Fallon/Miles/Amanda love-triangle! The only downside I can see if not getting the whole "Jeff is Jason's son" thing, which resulted in so many delicious "Vindictive Sable" moments.
