   Something very similar to this was already possible via serverless-express for node:

   https://github.com/CodeGenieApp/serverless-express

   This wraps Lambda's 'handler' function and allows express to run on top of it, essentially you get a node web server with no persistence between requests which usually isn't a good thing to rely on, but you can also kinda have that with persistent tcp connections.

   Similar libs exist for other runtimes as well.
