How razees expressed the battlecruiser philosophy

Did a razee follow the battlecruiser idea by keeping battleship-caliber weapons in a faster ship with fewer guns?

Yes in broad philosophy, but achieved by converting an existing ship of the line rather than designing a new battlecruiser-type hull from the keel up.

Removing an upper deck reduced weight and allowed a former ship of the line to behave more like a very heavy frigate. The converted hull retained substantial construction and large-caliber guns while gaining speed and handiness. The result followed the same engagement-choice logic used for heavy frigates and later battlecruisers. A razee reached that balance through conversion rather than a new design.
