No, that won't work.

First, without "Expect: 100-continue" in the request the client will send the 
body immediately without waiting for anything so there will be no chance to 
send the 101 until after the request-body.

And _with_ "Expect: 100-continue" we've already concluded that 100 must be 
sent back before the 101 and that will then make the body get sent as well 
before the 101 will be considered!

The Expect+Upgrade discussion thread I'm referring to can be found here:
