You are obviously a grown man and should not take investment advice from me, or anyone else anonymously on the internet, but I still think going all in on 2020 leaps would be a bad move. On the other hand I think they will likely be a good investment, and will probably buy some myself, I just think they are way too risky to go all in on. Before you go ahead with this stratagem I would encourage you to go back and review the "TSLA trading strategies" thread from Oct-Nov 2015. I don't know how to link it here, but I will copy and paste a few choice quotes.
MitchJi 10/30/2015 "Thanks for your post! I would never have considered J18s @$490-$500 without your post. You helped me formulate a plan. Hold our Mar 16 230's and 240's and cash, until it looks like a good time to load up on J18 490-500's in Nov-Jan. I am very enthusiastic about this strategy."
MitchJi 10/30/2015 "I think we are close to the bottom, so I don't think it's a good time to buy puts. I think it now is a good time for a long-term position with much more leverage. It's like counting cards, the further the odds are in your favor, the more chips it makes sense to put on the table."
Reading a little farther down the thread it looks like you didn't follow this strategy, but you seemed pretty sure of yourself at the time. Could you imagine the carnage if you had gone all in in November 2015 on Jan 18 $500 calls? This was during a period when the greater stock market has had a huge bullish run and Tesla has had it's challenges, but overall has performed extremely well as a company. Think of the confidence you would have had, if you could see just a peak of the future in late 2015 and knew for sure that in late 2017 Tesla would be selling 100k model S+X, and was sitting on 500,000 Model 3 orders, which was just going into production with rave initial reviews, and the S&P 500 would be 23% higher? You would have made that leveraged bet for sure, and you still would have most likely lost almost every penny you had.
