In this note we study possible derivation of new gravitational actions which are also invariant under a non-Abelian gauge symmetry. We start from a canonical representation of symmetry generators and define the corresponding canonical action which can also contain additional Hamiltonian constraints not related to local symmetries. The obtained class of theories possess between zero and some finite number of degrees of freedom. We discuss three special cases, starting with a theory with maximal number of degrees of freedom and finishing with a theory with zero degrees of freedom.
