Currently there is no plan to do this and I don't think it has a lot of value. One option is to write your own interceptors on both sides to bypass HTTP/2 stack. You'll have to handle deadlines, flow control, multiplexing etc. on your own. Essentially, you'll be implementing your own transport between the two processes.
