Using Beaglebone cape with RPi

[EEEnthusiast]

Folks
I have an existing Beaglebone cape and not enough beaglebone black boards with me. But I have plenty of RPi cards lying around. I need to use the BBB cape with the RPi board.
Is there some adapter board readily available to buy, which can help be bridge this problem?
That adapter card will sit over the Rpi and provide me with the P8 and P9 connectors of the Beagle Bone Black. RPi will be my host now.
