Is it permissible for a daughter to take a son's share if the father stipulated that, and do properties registered in the wife's name enter into the inheritance?

The wife's share is one-eighth due to the presence of children. The remainder is divided among the two sons and the daughter, with the male receiving the share of two females. The father's will that the daughter be given the share of a male is not enforceable because "there is no bequest for an heir," unless the two brothers agree to it. As for what is written in the wife's name, that has a different ruling.
