Yay!

Yes, it's possible :)

you can inspect all your subrequest's response bufs in your own output
filter and accumulate the overall buf size (i.e., the total length of
your subrequest's response) along the way (but not buffer the bufs
themselves).

It will not prohibit chunking as long as you don't want to send a
Content-Length header before sending the response bufs.
