cub coupler fittings with corny plugs!

[mr beer]

I found a tooheys keg coupler with male corny plugs mounted on the inlet and outlet on ebay


This would work great if i could fit out a CUB coupler like this: it wuld symplify all my connections as i interchange between cornys and CUB kegs:
but does anyone know where i could get the right thred connections? has anyone got a set up like this?
