Thinking of just making minor edits to a bunch of already-existing VSJ+ Koikatsu characters and releasing them all as a pack without bothering to change the card image and stuff. Not sure though because these edits are much less intensive than the ones I spent like a full week working on Would I be breaking some unspoken rule by doing relatively few changes and rereleasing a card.
Here's an example. Right is the easy to find Techy currently available online. Left is what I just finished with my edits. Only real changes are minor tweaks to the face / head shape, adding an iris overlay, adding some tears in her stocking, and giving her shortstackier proportions.
