Synchronous idoc to https scenario

Hi Gurus,

I have a below scenario

IDOC --->PI-->HTTPS, HTTPS response --> PI -- >IDOC.

Please let me know if there is a possibility that I can have asynchronous calls on the sender side (i.e. IDoc) and Synchronous calls on the Receiver side (i.e. HTTP) as the request sent by IDoc gets a response in return from HTTP with out using BPM ?

Reciever will send a tarnsmission report to PI and From PI the response will be send back to R/3.
