  Inspired by the newly observed $D^{(*)}(3000)$, and $D_{sJ}(3040)$ states, in
this work we study the production of $D^{(*)}(3000)$, $D_{sJ}(3040)$ and their
partners through the semileptonic decays of $B_{(s)}$ mesons, where the
light-front Quark model is applied to the whole calculation. Our numerical
results indicate that the $B_{(s)}$ semileptonic decays into the $2P$ states of
the charmed or charmed-strange meson family have considerable branching ratios,
which shows that these semileptonic decays can be accessible at future
experiments, especially LHCb and the forthcoming Belle II.
