But with fixed ammo pouches left and right (or ammo pouch left and utility pouch right). Something resembling this is already being knocked up by a couple of UK shops as demand is high for custom-made 'lightweight' belt kit. Roll-pin belt is better than the plastic buckle, especially if it is threaded back on itself to make it 'quick-release'.
The kit in the picture I linked to is actually made by Vanguard and is designed to be worn with the normal yoke and ammo pouches. The reason they leave it like that is so you add your own ammo or utility pouches as appropriate.
Regiment646 - if you could knock out a version of your 'Efod' pouches in this configuration (obviously in British DPM), you might sell a few in UK.
