I LOVE most of the ideas above. You need to look at dear what you can afford to learn if u need to, how much time and energy u have to learn it if you pick ones needing that, and also preferences. Also, take into considerations if u have any other special needs that could affect any of these sports too. And if they do, how specifically. Especially if you need training for it. You And keep in mind, the risk factor, and any gear costs. Not just of your original sport idea but, also, off any alternatives. Obviously your location may come into play too. I'll post more later.
