Not ever to my knowledge. Malone was brought in from his novels outside of soaps in 1991.
I can understand why a DAYS fan would love some of that, but for people who watched the more socially conscious Malone of the 90s (who definitely had flights of fancy, but they were balanced with gritty social stories as well) it was like living in Bizarro World. It went south almost immediately. I have a pretty high tolerance for camp and fantasy on soaps myself, but so much of Malone's 2003-2004 was very, very poorly executed. When you're spending a week in the never-before-mentioned 'secret tunnels' of Llanfair and watching as Blair and Dorian get trapped in a secret room full of Indiana Jones spike traps while searching for an all-powerful Indian diamond, all of this supposedly happening in Viki's basement, and the other A-plots are Jennifer Rappaport and Antonio Vega, my patience wanes fast. That being said, I've never forgotten any of it and it was a truly imaginative, demented time with some highlights and pluses amidst the chaos, far preferable to the nihilistic morass of Dena Higley.
