I mean yeah that's basically what high compression solutions like paq have done, depending on the compression level desired apply increasingly speculative and computationally intensive models to the block and pick whichever one worked the best.
C has some of the best static analysis and debugging tools of any language, but all of that's worthless if you don't use them.
