Thought I'll give a post 24 hour update. I have no idea if it's a lot, but there were 120 responses.
81% would like the R2 1.5u pipe key with ₩, so I will get it added to the kit. I'll also ask about the possibilities of added a R1 1u version too.
61% said no to the punctuation and numbers. I'm fine with that - It would raise the kit price probably by 80%, and open it up to not that many more people (who knows how many of the 61% would join if they were added too).
I'll start speaking to vendors too. If anyone has recommendations, let me know! I will definitely be looking for US, EU, and Asia.
