I can see Pegasus evolving into one of those ... first remove X turret to add length to the flight deck, then Y to add a bit more and a larger hangar ... then some years later remove A and B, add catapults and you have a half-decent small carrier.The Cruiser/carrier sounds like an 'interesting' experiment, there was a bit of a designing fad in the 20's and 30's of mixing a cruiser and a carrier
For example was a design the US was actually looking at in the late 20's early 30s.
But I assume she's very much a testbed design and would be put under the list of "Things to never repeat." The RN's not got a 'light BB' out yet but HP machinery and other advances...forshadowing much?
They're finding out what can be done when machinery weights are not so high...
