I found how to install origin silently:

And maybe Battlenet for Overwatch?

Actually I see that you install chocolatey, so You could install steam and origin with it.

I don't think Battlenet can be installed with chocolatey. Origin should be easy enough. Feel free to submit a PR if you are interested, otherwise I'll do it in a few days.

I think i did to many changes in single commit, but You can see my custom version here: ipepe@4ceafa4

Nice work! I'll look into it and try to incorporate some of your stuff if you don't mind :)
