Even without looking a a specific recipe, I would still say yeah this will probably work. Belgian recipe grain bills are not really weird in any way. For a a typical dark Belgian ale, there will be a lot of Pilsner and Munich base malt, plus some CaraMunich for body/sweetness. Just up the hops to 25-30 IBU, throw in some English yeast and call it a Hobgoblin clone. It won't be exact (you might need to add some toasted grains like Biscuit or Victory) but it will make a great beer.
