Hello there, thank you for reaching out and thank you for your kind words! I would love to help on this but currently i don't think i could take this one on.
Ive look in to this a bit and it does seem there is an psd exporter script available, however it does not import psd to aseprite.
When looking over the script and it looks really quite complicated and they seem to be creating a binary file from scratch. Basicly this process would need to go the other way looking at a binary file and taking it apart which might be doable but I'm not sure how long it would take to make sure it's working correctly.
Here is a link to the script I found that exports to psd though! Just for reference.

This might be something that eventually gets added to aseprite though again it's really quite complicated to get it working correctly. Espcially if Adobe changes anything in their file format. Something to look at in the future for sure though!
