No. The whole point of the ecoboost program is to provide bigger engine power at smaller engine efficiencies.
The current cyclone block was designed for as much as 4.0L of displacement. Using the 2020 Raptor's numbers, this means the engine can scale to 515hp, 583lb-ft (a bit less due to losses), without any stroking or other neat tricks. As it stands, the Ford GT gets 660hp and 550lb-ft from 3.5L. Scale THAT bad boy up to 4.0L, you get 755hp, 629lb-ft.
They have gone beyond the original intent (V8 power at V6 efficiency) and are producing big block power in engines that can still be operated efficiently. Building a V8 ecoboost would be opposite of the purpose of the program, and you definitely don't need a V8 to make the power any more. Ford is actually moving in the opposite direction... I would expect to see a 4-cyl F150 that makes decent enough power within two generations. Mercedes has a 2.0 making 416hp, 369lb-ft. The Focus RS made 350hp/350lb-ft. Develop a stronger block and higher thermal capacity cooling system, you can move an engine like that into the F150.
Why not V8? More moving parts, more friction. Ford has built small V8's with high tech (ex. 3.4L SHO), and likely surmised there is no good reason other than exhaust note to go with the V8 format in boosted engines. A V4 or V6 has fewer parts, a smaller horizontal footprint, weighs less, and bumps the CAFE numbers, with or without boost.
