Shou, Sheng, and Samples in Pumidor

Hi y'all, got started with a small Pumidor recently, not primarily a pu'er drinker but have been stacking up on enough cakes to justify a small one. Right now, it mainly consists or aged Shengs, alongside a young sheng, a shou (Lumberslut), and some samples of varying pu'er types.

I've definitely heard to separate the sheng and shous in my pumidor, but obviously I'm not going to make a whole new pumidor for my grand collection of 1 single shou. I also have only the size 60 bodeva packs.

My question is, how well would the shou fare outside of a pumidor, versus if I put it in an open mylar bag inside of my pumidor (which I've heard people do)?

An addendum to that, how do people store their samples? Right now my samples are just in a closed ziplock bag, and then inside of an open mylar in my pumidor.
