It's technically correct, but it sounds weird and non-native to me. It requires me to jump through mental hoops to explain how it makes sense. For easy communication, I'd recommend sticking with "wanting" in this situation.

(though I'm not averse to using awkward phrasings or the like in casual situations where clear communication isn't the number one priority. At the moment I'm on a crusade to bring back "thrice" and {h,th,wh}{ence,ither}. )

Thanks! I actually moved to the UK exactly one year ago to improve my speaking/writing English skills, and every suggestion helps. I hesitated when writing this comment and went for "willing" because it sounded good (not a very good way to choose what word to use…).
