Well, considering that there apparently are opposing equal forces from the dual pistons on the camshaft at all times, folding it into a V shaped engine block should be possible... Will probably look a bit odd, but should reduce width... It might actually be possible to put the two halves of that engine side by side? Making a very narrow engine instead...

yay, 1907 technology! Opposed-piston engine - Wikipedia, the free encyclopedia
I keep seeing these pop up, they have their own issues, either two cranks, or really long connecting rods for the "far" pistons, both of which increase rotating mass and don't work well for higher RPMs.
It's not like the "force" that is held in by a normal head is lost.

Yeah, it's not that good for high RPM's but the proposed use in the link is for trucks and similar, so RPM's isn't an issue... Could be for bikes through...

Well, considering that the "modern" 4 stroke engine has it's roots in 1861, it's actually to be considered "new" and "hightech"...

Oddly enough the most efficient engine made is a 2 stroke diesel. (bigger than most houses) Most powerful diesel engine in the world Over 50% of the fuel burned gets turned into motion.
Simpler is often better.
