Trust your gut. It's usually right. It seems like you want to clear out the un-displayed Hasbro stuff, so go for it. Use that cash & space for more important things. Always save money for those intangibles, like going out on a good date with your wife.
Take it from someone who's been there, and collects various lines, SW and non-SW. There's no need to "quit" Hasbro(though I've cut down drastically on it). I recently bought Elis Helrot and the new Bossk & IG-88, and they're the best versions of those characters for decades to come. What remains are my absolute favorite, cherry-picked figures. There are even a few vintage figures in there. No need to be all-or-nothing, only Sith lords collect in absolutes.
What do you want? Imagine as concretely as possible, what shape you'd want your collection to take. Don't let the hype-machine influence your decisions, play by your own rules.
Forget completism. You'll never have it all, and in the long run, you probably won't want to. There's always something cool in the horizon that'll make you want to shove your "less desirables" off the shelf to make room!
Survival of the fittest. Let your shelves be a canvas. Don't let inferior pieces bog down your vision.
Healthy speculation. Another key trait in collecting is to develop a good eye for what's going to be 'rare' in the future - not for scalping, but to save yourself from paying one! Now, this pertains more to the high-end stuff, like Kubricks. It means the difference between paying less now, or several hundred later. For Kubs, it's probably best to order them early, especially by the case, if you want chases.
Of course everyone has different tastes and strategies, but one thing we all have in common is having to balance limited resources: money, space and time. Balance them more to your favor, and get what you want.
