sorry for the slow replies!
Firstly, yes, these assets are a passion project, so I'm planning to handle their distribution independently, without a client as a middleman. However, I also work on commissions, so making something else which would be custom is definitely a possibility. Your idea does sound different and potentially interesting to work on.
Secondly, that said I'm pretty busy in the nearest future (for the next couple of months at least), so I'm not able to take up any new work very soon.
If that still works for you you can always contact me via email kubjansson@gmail.com
