Hi everyone,
I don't know if you're still working on this, but last year I actually spent some time collecting lots and townies to create a medieval neighborhood (Willow Creek, Newcrest, Windenburg, Brindleton Bay). I checked out some stuff from other simmers and altered it to fit my way of gaming.
But I mostly used cc-clothing and some cc-objects for essential furniture (toilet, oven, crib etc.), so I don't know if this might even help you guys. If not, just ignore me haha
But if you're interested, I highly recommend zx-ta's tumbler (https://zx-ta.tumblr.com/tagged/medieval-cc). She converted lots of stuff from TSM to TS4 and it's really awsome!
I have a savefile of my game, but I don't know how to upload any pics :#
Anyway, let me know how your project is running! I'd love to help and collaborate with u
