Nice idea C.P!
　 he reed setup as you show it may work really well but the fabrication would be a mission unless it was a .40 sized engine because the reeds would be TINY!! How about a single reed that points up at the cylinder, with the carb and induction tract also angled steeply up... starts to sound interesting, especially if you build a stuffer that sits over the reed taking up the dead space <made quite a differecne when I tried it)
