Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  investigate parameterizations of both database instances and queries that make query evaluation fixed-parameter tractable in combined complexity.  introduce a new Datalog fragment with stratified negation, intensional-clique-guarded Datalog (ICG-Datalog), with linear-time evaluation on structures of bounded treewidth for programs of bounded rule size. Such programs capture in particular conjunctive queries with simplicial decompositions of bounded width, guarded negation fragment queries of bounded CQ-rank, or two-way regular path queries. Our result is shown by compiling to alternating two-way automata, whose semantics is defined via cyclic provenance circuits (cycluits) that can be tractably evaluated. Last,  prove that probabilistic query evaluation remains intractable in combined complexity under this parameterization.

I am writing a research paper on a idea Combined Tractability of Query Evaluation via Tree Automata and Cycluits.
