First, they should be obtainable in-game but that's a whole different issue.

They should at a minimum absolutely make the emotes available for purchase separated from the statue some time after the physical item's run has concluded, this also should be the norm for digital bonuses tied to other old merch that is no longer produced. I wouldn't blink an eye if my soundtrack-exclusive minions became available again later, I wanted the blu-ray that's why I bought it. And I know the meme of buying an emote with a bonus statue has propogated enough that the brainrot has taken root by now, but we all know SE would make more money selling the emotes in perpetuity as standalone purchases than they do from overall purchases of limited time and (up for personal debate) overpriced statues.

And for people that get hung up on muh exclusivity, you got to have the emote/minion/orchestrion/etc YEARS before others did and got some nice actually limited good(s) that after a certain amount of time fewer and fewer of which will exist in the real world at all, get some help.
