I think boilers should be able to boost steam up to a higher pressure for a lower fuel cost.

It could be something an advanced tier 2 boiler could do.

What is the argument for reducing the fuel cost? The reduced "time" required?
What is the primary reason you want this? There are already low pressure and depleted steam reclamation mechanics so I'm uncertain why you would want this included.
