Hyper-Berkeley cardinal

Let define cardinal $\kappa$ as hyper-Berkeley if for any transitive set $M$ what $\kappa$ $\in$$M$ exist elementary embedding $j$ where fixed point $\lambda$ above critical and $\lambda$<$k$.

  1. This cardinal equconsistent with $ZF$+"club berkeley cardinal"?
  2. Are consistent to $ZF+$$BC$ (berkeley cardinal)?
