No, he can't. Will has a duty to ferry the souls, which is how he spends his 10 years at sea. If he abandons that duty, he ends up all fish-like, as Davy Jones did. But because Will doesn't look fish-like in the AWE epilogue, he doesn't abandon his duty. Therefore, it is impossible for Will to return without screwing the way the Dutchman's curse worked(which would definitely cause confusion).
