Last Unicorn did in fact produce a Dune RPG. They were then brought out by Wizards of the Cost. Wizards/Last Unicorn released a limited print run of the Dune rulebook.
There were rumours of changing it d20 before anything else was published, but the line folded with further rumours of difficulties with the licence. This was a bout the time the prequel novels were published, so the Herbert estate may have considered the two to be incompatible.
