The sail I have in mind is often referred to as an A1 as in Asymmetric Racing Spinnakers | Doyle Sailmakers
. Not having done the math, Ii would think an A1 on a CAt27 with a four four sprit would have 70% or more area than a cruising chute. combined with the convenience of a furler, this area makes the sail more useful in the light to mid winds. In higher winds, the price of sailing with a genoa is not so bad...
I agree your cruising chute is providing excellent drive in your photo, and a larger A1 would be dicey, but winds in the high teens to low 20s is not the sweet spot where most sailors are looking for more go anyway.
