No. Investors are no going to be happy about dead equity having over 10% max (total) and will very likely take steps to dilute you if you try to leave with that much. With 3 founders, I think the max you can hope for is 3-4%. But get an agreement from the company that neither of the remaining founders can receive additional shares for 2 years. I've been in this situation before, and that clause is a pretty effective way to protect against dilution. But mainly, but not sticking out, you avoid a really punitive recap that could make your stake round to zero.
