I tried, several times, to do what you are contemplating. But like Michael Corleone so famously said in Godfather 3:
Back in '97 I had just graduated from University and decided to give away all "extraneous" things which meant a whole tub of G1 toys (including metal plates on the trailer floor Prime, painted Matsushiro emblem on the wing Jetfire, Wheeljack, ruber hose not cracked Shockwave, and others) ended up at my church's toy drive.
10 years later my newborn son "bought" me a Classics Jetfire which acted as a gateway for re-collecting everything I gave away.
At present I've sold off all my CHUGS/Bayverse/TFA in favor of strictly G1s and MPs. The journey here was costly but fun and like I said I tried a few times to give it up. Yet I wonder if things would have been different if I stored that tub away.
So my advice to you is invest in a good solid Rubbermaid tub that seals, fill it up with your plastic crack and stick it in your crawl space/attic. If anything it'll be cool to rediscover them in the future especially if you ever have kids.
