I would love to see physical copies of
Navier Haruka 2T works. His art and details are very rich, one of the best art-style I have seen so far. I understand his works are mostly in Doujinshi, so a limited edition of his work as Doujinshi Box Sets would be a perfect solution.
My Harem Fuckademia (1 donjin - fully colored)
New game+ (3 donjins volume)
Succubus Delivery!! (3 donjins volume)
This totals about 256 pages, maybe a bit too many, but a higher price tag could justify that.
