Anything can be done, but imho, way more work than it's worth. If you want another F150 with the 3L, would be easier and cheaper to trade. 1 example of a diesel repower that is somewhat popular= 2.8L Cummins to the older Jeeps, BUT, Cummins has done a lot to make the swap easy. I agree with you about liking the "diesel experience" over gas. These 3L diesel motors are sweet, Ford,GM and FCA.
