Ikea Billy with Benno "around the corner"?

Hello,

I want to create a corner solution with Billy and Benno (CD shelf). One Billy (80x30x202) should stand along one wall and several Bennos along the other wall. A Benno should be placed in the corner, rotated by 45°.

My question is whether this is possible with the corner fittings available from Ikea?

BILLY
Corner fitting, galvanized

On the website, it says "Suitable for BILLY bookcase, 40 cm wide and 28 cm deep"...

Thanks for any tips.

Stephan

I do think it will work, but don't ask if it wouldn't be enough to connect the parts on top with a simple flat connector from the hardware store.
