Sure thing! Serverless architecture is an interesting thought.
I didn't include this in my write up but I figured out a few tricks for generating as many Twitter accounts as you want (their current safeguards against this are not very strong).
I think adding some components that auto generated accounts in addition to something like lambda would make this theoretically limitless in the number of accounts it could run.
I'll leave it for those who have interest in working that out.
Interesting this isn't gaining more interest.
Also interesting how you could extend this with serverless architecture to be unkillable and massively scalable
