I have very limited understanding of how to create a mod for Stardew Valley, but doing the art is easy enough. I imagine that this would be post-constant so his dialogue would reference the other survivors every now and again. That, and you'd find a TON of the worst puns you've ever read throughout.
if I knew how to do this, I'd add Wilson after you complete the Terraria quest to imply he got to stardew through the Terraria crossover
Loves: Complete breakfast, green tea, Solar essence, void, fire quartz, frozen tear, earth crystal, petrified slime, star shards, lucky lunch, ancient seed, rusty cog, coffee
Likes: red mushroom, sweet gem berry, prehistoric handaxe, dinosaur egg, coal, gold ore, bat wing, squid ink
Dislikes: Algae soup, magma cap, leek, salad, joja cola
Hates: cave carrot, carrot, poppy, bug steak, Torch (they remind him of the constant)
Neutral: monster musk
I give my full consent if anyone wants to make a wilson mod to use these. Just please give me credit if you do so.
And, you know, don't feed my stuff to ai
