It's entirely possible... In fact, I'm pretty sure that there are more than a few very wealthy people willing to place bets on that very thing... maybe not everything, but upwards of 1-3% of their wealth.
Now, actually getting in a room and talking to those people and getting in on the execution of that idea... that's a different story.

It's technically feasible but practically infeasible because parasites won't willingly leave a host.
