anyone tried fitting a medium green egg in a wall-mounted tabletop / shelf

Greetings from the Netherlands, where the weather has just turned great for BBQ (well, always a good time for BBQ :-)

We have just gotten our Medium BGE and while first being completely convinced about the WWOO (www.wwoo.nl) we are now more tempted to go for fitting the BGE in a wall-mounted shelf / beam and standing on top of concrete cube.

See picture attached here (am aware this is a Mini, I want to apply this design to my Medium BGE):

Anyone tried this and has design / blueprints? Any recommendations / suggestions for design and materials?

Best,

Arjen
