Hmm, I can understand that. Oh, BTW, the picture isn't showing.
Still, in the whif-verse it's perfectly plausible. The Lockheed P-7 was supposed to be a stretched and improved P-3 with new engines; only the stretches ended up turning it into an entirely new aircraft and the cost went well above what the USN had signed for, so that program was cancelled. I wonder if the propulsion portion (GE T407 turboprops driving 5-bladed propellers) of that could be applied to a "stock" P-3.
Note: A bit more googling shows that an improved version of the T407 is the GE38 that will power the CH-53K (roughly a 25% increase over what was intended for the P-7A). I could see a flat-rated version of that engine and a more modern propeller used to upgrade P-3s, particularly variants that need more power than the T56 supplies.
