Thanks for the vids Drop bear. I know I am sounding like I am just blowing old wind but I was always taught and drilled to end an altercation in a SD situation, or anything other than a ring event, quick as possible, with the least strikes, techs as possible. I thus have concern with this idea of getting in sprawl and moving about wailing on the guy and "throwing as many as I need" - this makes it sound like you seem to have an on-going window of opportunity here, both to inflict damage and to avoid it yourself either from the guy or others.
I ain't no SD expert or anything of the sort but have trained with those that supposedly are and have a bit of real world experience (I simply state that as many people and MAsts don't, including such SD experts...). I have been in real SD situations where I have been attacked (one involving four assailants), one situation where I immobilised a fleeing shoplifter who had broken through several security guards and members of the public and when younger several street and party fights and altercations (the street fights and pub brawls all which I could have avoided but was younger and less inclined to being sensible). I have a pretty good idea of how quickly things can go south and how brutal things can be. That said, I do not have any involvement where a gun was involved.
I am a solid judoka alongside my years of karate and strike fighting and have used submissions, arm bars and guillotines in freestyle and mma tournaments and see myself adequate/average in the grappling game, I am not coming at this from just an ignorant stand-up perspective. All I am saying from my training and actual real experiences, I would not be advocating this idea of "feeding punches and knees etc" in some sprawl or otherwise going to the ground or tying myself up in a move that took more than a second or so to employ. Whatever it is you are going to use, it needs to brutal, it needs to be sudden and it needs to be over.
