Obviously it's tuned for a very different application. It would be easy enough for Subaru to at least make the same hp/liter with a 2.4 NA tuned for the BRZ, so 246 N.A. horsepower right there.

You would really need a square setup to go higher and this engine is not like this. It has a 94-millimeter bore and an 86-millimeter stroke and it was designed for torque, not horsepower.
Whut? More oversquare is generally "revvier" and has more potential for higher-rpm power vs. square or undersquare. Same stroke as FA20 so really no more potential revs based on piston speeds/accelerations, but now there's a lot more potential valve area for better breathing without having to resort to greater valve lift or duration.

As you suggest, at the *very* least it would give a good boost to torque everywhere even if they kept the same heads and valves which would limit gains in high-rpm power.
