Can a will be incorporated into a partnership deed?

dear learned friends

i have an important query: can elements of a will (means distribution of assets after one's death) be incorporated into a partnership deed?

for example, a and b are partners of a firm. they add a clause in the deed that all of "a"s properties after a's death are to go to the partnership firm.

is this permissible in law? if not, why? please let me know the citations.

thanks

yours
