A core aspect of the Dragon Quest franchise revolves around a staunch adherence to its own tradition. Unlike, for example, the history of Final Fantasy, which proves a series can be endlessly self-referential while still pushing to evolve, much of Dragon Quest has stayed the same. The music, art, sound effects, and monster design are removed and tweaked slightly, if at all, only to be packed away again for later use. It's part of what makes the series what it is, and to mess with that formula now would no doubt alienate fans.
