That seems like the best route for Basic combat. If you want, you could allow it with a limitation (only for escaping grapples). Call that a -50% limitation and it'll cost the same 1/level a technique does and thus should be more or less balanced against characters who have taken some more complex Martial Arts path with Unique Technique.
