Are the bodhisattva vows better suited to the lay side of Buddhism?

As a practical observation, if one were staying below arhat for the initial aeons, could monastic living limit the efficacy of a bodhisattva? Since that goal heavily rests on seclusion, and both the wandering and monastic models were developed to enhance seclusion, shouldn't a different, more open model of monkhood exist? They should be able to have kids at least for example, since it would help them to help more beings.
