Sign Language set for Common Terms in Cosmere!

[ZMPr0wler He/Him]

So I was watching the latest video of the London Con, when Brandon, Apologizes for the weird fantasy words. Around the 58:15 point in the video. I wondered would it be possible to make a standard for some of the bigger ones like a set for each planet/System, Or other ones that are common, If you are someone that talks with another in Sign of any language, as I know that ASL is the standard for English readers. I was just thinking about this, And thought having a set one for big thing would be really cool to have in the next arcanum unbounded or something. 

If this is pushing to much or thinking about something that is not needed you can cut this post. Thank you again and just an Idea and thought.
