You appear to be the first person crazy enough to contemplate this.
Frankly, having taken the existing engine in and out myself a couple of times, it seems unlikely that there would be room for a bigger one.
If a thou can be squeezed in without hacksawing out inconvenient bits of chassis, the exhaust ports may well have the wrong spacing for the frame and, even if they don't, the constraint imposed by alignment of the drive sprocket could cause them to clash with the frame anyway.
A few measurements taken beforehand may prove the job to be impossible, but if you're unlucky they won't and you'll only discover something makes it so when you actually try it.
