What's wrong with multiple engines? a smallish 2 cylinder and one twice as large? Make them both atkinson style, or diesel (I don't think sterling is on the table here), and each can be de-clutched from the transmission individually or run together. I'll skip further delving into the driveline details there, excepting that lets assume it can all be conveniently button operated and not aggrivate any existing conditions (and not cause serious losses).
If you have, i.e. a 500cc and a 1000cc engine, you can choose between 500cc, 1000cc or 1500cc, whichever is most efficient for conditions. If you can tie 3 small engines together, i.e. a 250, a 500 and a 1000, then you have 7 displacements to choose from. 250,500,750,1000,1250,1500,1750
