It's not really a question of unplesantness or honesty, more that it's self-defeating: your intent to get the best of both worlds with participation in open source and getting some reward if your work is used commercially is reasonable, it's just that when you write your own license, especially by trying to combine two existing licenses, you're most likely going to wind up with neither (as in neither open source projects or contributers will be interested nor will commercial companies, and anyone who does will be more likely exposing themselves to legal risks).
