People need a compelling reason to switch from the tried and tested to something new and unproven. So you need a compelling feature/benefit. But I cannot see what it is.

Is your approach going to significantly improve performance? Doubtful. You really need to prove this.

Is your approach going to make it easier/faster to write code? Definitely not, multithreaded code is many times harder to get right than single threaded code.

Is your approach going to be more robust? Definitely not, deadlocks, race conditions etc. are a nightmare to fix.
