No, it is not so simple. Anything which approaches your goal is fancy law and you will need to speak with an attorney to help you through as the area is extremely technical and not entirely clear with court cases coming out against certain areas and treatments. I'd have to look through my case file, but recall an important IRS ruling fairly recently which put the kabosh on many prior cases allowing it.
The term you might want to search for is SCIN (Self cancelling installment note) to give you a better sense of what is happening. The law is changing rapidly in this area and it is definitley not a do-it-yourself project. There are (or were, I haven't done any continuing education after the recent changes) requirements to base the note on life expectancy and there was a sliding scale of risk/benefit depending on how long until the target person died. Also, there are some very sophisticated estate planning techniques which create a plan using this technique and simultaneously setting up other vehicles with a reverse sliding scale of risk/benefit to make the value of the planning very predictable.
See the guy. Not just a guy, the guy. The guy who does this all day long every day and charges a ton of money for his expertise.
