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.

And then, when nobody wants to implement all the compression algorithms in a compressor or decompressor, we end up with files out in the wild that only pick one of them anyway.
