Not super soon since there are higher priority things to work on right now. But it's technically possible now, and I do have some ideas.
I fully expect the customizable NPC to come out before any other NPC ideas like a blacksmith. There are enough request for it to be higher priority.
Lore wise, I think Silverpine needs a carpenter, builder, or some similar trade that can explain who erected Silverpine's buildings in the first place. Also, a new vendor for building related items like furniture. Aldric can afford to lose some inventory, he has way too much stuff.
