So, basically, you want what the F-35 was supposed to be when LockMart originally submitted the designs before Boeing decided to bullshit to congress that their entry could do all three of the airframes' roles?
The Original 'F-35' (before it got that number) was supposed to be the F-22, but with improved stealth by fixing the F-22's coating (and better angling) as well as improved engines and open-architecture computer systems.
The Airforce then decided they needed an F-16 replacement more, causing the pre-universal F-35 to begin to take shape. The Navy then stepped in and offered to go half-in on the Twin-Engine design if it was redesigned for Carrier Operation, which the Airforce thought was a good idea, so the 'F-35' became the single-engine F-16 replacement and what became the 'F-37' proposal became the twin-engine F-15C/E and
Process being as process is, Congress demanded that the Airforce and Navy hold a competition for the entire thing, and the Marine Aircraft replacement had to be part of the same program - winner take all. The Airforce objected to no avail, since they already decided on the F-35 and F-37, while the Pentagon wanted the Marine aircraft to be made by someone else.
Then Boeing, which only had one of the three aircraft designs (the VTOL would-be F-33, ironically the aircraft the Pentagon wanted for the Marines in the first place), panicked and lobbied congress with physically impossible bullshit (claiming their single airframe could do everything), which Congress bought like the idiotic low-IQ fudds they are. And that's how the Joint Strike Fighter came into being.
Boeing still lost since LockMart's 'unholy abomination' (which is Skunkworks' name for the F-35) ended up theoretically
capable of pulling off the congress mandated bullshit in a vacuum, whereas Boeing's offering failed to even do that.

The Marines' component of the program was at the start supposed to be an entirely different aircraft, the F-33 or F-36.
