Elise,
The main purpose to use other plugins instead of yours is the limitation of changing variation images based on color when you have size + color.
But there are tons of plugins that can fix this issue for me, so all that I want now is to help me not load thousands js-s for the same reason.
If it’s not possible, I will understand.
Our JS scripts are not loaded when they are not used. You can insert the script key and plug out it. You can find the option in the Theme Settings > Performance > JS > Advanced > Advanced scripts controls = ON and then find this field: https://monosnap.com/file/OhMfgKvnJqvr2w4qxgt43zKc3BQBnB
