Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: This work deals with the expressive por of logics on finite structures with access to an additional “arbitrary” linear order. The queries that can be expressed this way are the order-invariant queries for the logic. For the standard logics used in computer science, such as first-order logic, it is known that access to an arbitrary linear order increases the expressiveness of the logic. Hover, when  look at the separating examples,  find that they have satisfying models whose Gaifman Graph is complex – unbounded in valence and in treewidth.  thus explore the expressiveness of order-invariant queries over graph-theoretically ll-behaved structures.  prove that first-order order-invariant queries over strings and trees have no additional expressiveness over first-order logic in the original signature.  also prove new upper bounds on order-invariant queries over bounded treewidth and bounded valence graphs. Our results make use of a new technique of independent interest: the application of algebraic characterizations of definability to show collapse results.
