Anything heavy, would add to the fuel costs and purchase price.

Or, could you power a Gemini chassis, with a more powerful engine?

No idea, I think you would be able to somehow, The Paper Bus itself was a Gemini 2, I just edited it so it had the Plaxton Elite Front/Rear, I think the Chassis would have to be Altered to accommodate the Bigger more Powerful Engine, but I have no idea when comes to this Area of a Bus, I'm sure someone on here would know if the "Prolific Idea" would need a New Chassis or Not.
