What about pins as modified entangles? break the entangle break the pin. then for how effective your pin is you just pay for the extra level. Some pins would probably have hth damage as well (stun only) because you can't breath in them (torso crushing chest.) and are very hard to get out of. (the most effective pin I've had is myfeet near my head with the other guys weight entirly pushing my legs down further. there was very little I could do (he was larger than me so I couldn't just turn) and I didn't have the support to kick out- all the while I can't breath.
Now as for signiture/ finishing moves
just an extra couple of hth classes for that specific move. NOTE: not csl's, they should be dealt out only for technical mastery of the game.
And I would only allow CSL's for specific manouvers or atleast discourage full Hth CSL's
Just like the video games I would divide the different manouvers into: arial, grappling, ground etc
or have the csl's in different catergories like rough neck, fast, technical, powerful etc.
