Reinfection cases are extremely rare. Can you point to any that ended up on a ventilator? Of those (assuming you can find any) how many had double digit IgG antibodies verified recently?
They are rare in the sense that there have been few instances so far. The reason for that is there are few instances of a second exposure to the virus after a period of 6 months or more, which is usually how long it takes for the antibodies of coronaviruses to dissipate. The Jewish communities in Israel and NY/NJ are writing the book on this, and the anecdotal evidence suggests that reinfection is not rare at all. I don't know how many have been vented, and I don't know their ages, the severity of their first infections, the amounts of viral load they were exposed to the first or second times, and much else about them. Neither do you. Which brings me to my point.
You. Are. Rolling. The. Dice.
Everything about exposing yourself to intentionally get reinfected is a gamble. Do you know how exposed you were the first time? Do you know if you have any lung tissue scarring, any clotting, or any residual stress to your heart? Do you have any idea, or any control over, how much viral load you will be taking in the second time? Do you know if there were any contributing factors to your relatively light infection the first time? Do you know if there are any factors which can put you at greater risk now?
I'm not saying this ends badly. I'm saying you'd be writing the book. You'd literally be gambling your life. And this isn't Russian Roulette, with binary live or die options. There's a whole lot of ugliness in between.
