Probably, but modifying hardware to solve a software problem is really ugly and even then, the MotionPlus itself isn't the problem. Newer Wii Remotes (not all of the Mo+ ones, but a subset of them; model number RVL-CNT-01-TR) don't have a feature that old homebrew libraries were using to communicate with them. It wasn't an officially designated way for them to operate anyway, so it didn't break compatibility with commercial titles at all. Homebrew compiled using more recent versions of the library is able to communicate the "official" way and works with the new models. Anything that doesn't work with your hardware just needs to be recompiled.
