The Potter Villager could use the Pottery Table as its job block and buy/sell clay, bricks, terracotta, dye, and decorated pots

This would overlap somewhat with the Mason, but no more than a Weaponsmith and Toolsmith would overlap I'd say.

Also a Glassblower villager who uses the Kiln could be cool, they could buy/sell sand and glass related items, including stained glass and bottles

No plans for Villagers at the moment, many villagers currently have clay/brick/terracotta and some have sand/glass related trades too. It may be something we look into eventually, but not something we're interested at the moment, especially because of how tedious villagers can be to balance due to their broken mechanics.
