How much Feynman would you add to your Offspring?

If you had the option of having your offspring be N% randomly selected dna from feyman (giving up you and your partner's contributions), what number would you choose? If everyone chose 5% for a few generations, the world would get quite a bit smarter. Going all the way to 100% is not really adaptive - but seems like 50% would be a good start.

Obviously this is just for the first generation - later on you would want to reduce it to avoid inbreeding among psuedo-feynmans.
