My Classics Jetfire has started yellowing.

I already have Generations Jetfire and I intend to get Siege Jetfire, so I'm not sure if it's worth replacing Classics Jetfire. I do like the Classics Jetfire toy so I don't want to be without one; if I choose to get another one I would sell my current one (obviously at a cheaper price).
Hhrrmmm... might wait until after I get Siege Jetfire to see how I feel... having a 3rd CHUG Jetfire might negate my desire to replace my Classics one. <rubs chin>
P.S.: Speaking of Jetfire, apparently Harmony Gold's Macross licence expires in 2021. Anyone reckon this would allow Hasbro to acquire it and finally do things like...
* Make a new toy-accurate Jetfire toy
* Obtain a new Macross VF-1S mould and repackage/repaint it as Jetfire
*
Reissue G1 Jetfire
if the mould still exists
