i think lava relase of son is a tailed beast skill like the ink of bee (by the way bee is death?? they estracted gyuuki) so if you have the tailed beast sealed or at least part of his chakra you can use lava relase thank to the beast (naruto ask son the chakra) the rest is the same principle of fuuton rasenshuriken only with a different nature.
