The Manx tank has a very shallow tunnel. You would end up with the tank perched way on top of the chassis with loads of daylight between it and the engine - or you would need major surgery on the underside of the tank.
There are alternatives, with slight mods at the rear you could fit the Metisse / Triumph style tanks from the 60's / 70's and a GRP tank would be a lot cheaper than an alloy version !
