The first major isomophic keyboard, Jankó's, was allegedly praised by Liszt. But not enough for him to start all over again.
Jankó was a more than competent pianist himself, and had thought about these issues. You can reach everything you can on a normal keyboard and many things you can't, and the multiple ways to play the same tone gives plenty of ways to solve fingering challenges as well. The problem is no one is used to it, and no one wants to start out with it since instruments with the layout are extremely rare.
