Possibilities With Udon

I have a game type that I would like to create that is meant for a huge world. I want to create a game, however it requires me to take random avatars in the world and create motions for them. Do you think that with Udon that I could create a Variable that is constrained between to offsets?

For instance, I am going to tell this Avatar to move to this location. Some avatars arms are constrained to the sides, but the avatar moves like a player. Would i be able to randomize an instance between walking distance? For instance 10 Meters going left, then a random angle integer between 0 degrees and 359 degrees on an X plane?

I want to also know if that will impact the file size of the map as well.

Thank you for reading!
