I like the idea of the HFWD. Simple, no F/Rear ratio problems. and ought to be easy to mount. That "easy to mount" used to be a JD specialty. In fact, I've got a story about how easy it used to be to swap JD options...
Many years ago our JD530 tricycle almost did a spinning backflip when we were plowing and hooked a rock.
That was a crisis for our family so we ran to a tractor junk yard and bought an old "used but good" complete wide front off an older 2 cylinder - probably an old JD A.
The next day my wife & I removed the tricycle wheel and bolted up the wide adjustable front. It was real simple straight bolt up exchange, didn't require any extra parts, and was done in a couple of hours. All the bolts and holes were already right there in the castings. There was some nice interchangeable engineering in those days.
We still have that tractor and that power front end is still working fine. For that matter, the old tricycle front is around somewhere in the weeds. Never throw a tractor part away.....
