Very difficult indeed.  The factory went from an I5 to a V6 because
they could, and have the luxury of engineering all the pieces to fit
that way.  Converting an existing I5 car to a V6 is a whole another
story.  If you look under the hood of the two and compare, you'd find
that just about everything is different.  Not only is the engine
different, The location and shapes of most other components such as
radiator, various reservoirs, fuel injection system, hoses, lines, exhaust
and input piping, mounts, bracketry, wiring, electronics, ECUs, even
the instrumentation, etc, etc... are all different.  Even if you have a
complete donor car with all pieces intact, I'd imagine a lot of fabrication,
welding and cutting, and a lot of adapting would be needed.

If you have an unlimited amount of time, money, and patience then
anything conversion is possible; some are crazy enough to do it.
It makes less sense to go that route (as opposed to a I5 turbo
transplant into a 4Kq, which is "much easier" and have more performance
potential, but still by no means trivial).  But hey, some will do
anything just to be "different".
