Yes, if you had seven nodes b1-b7, you could give b1 7 votes and everyone else 1 vote. Total votes would be 13 and quorum would require 7 or more votes. So as long as b1 was a member of the cluster (with its 7 votes), there would be quorum and others could do whatever they like. As you say, to reduce the likelihood of b1 failing you may want to just have it join the cluster and do nothing else.
