I don't know, the principles can work together well, some of them, anyway. The principles of a good punch come from a good base, at least the way we train. In grappling, you have to have a good base, at least the way we were taught. As an example of the blend of the two, look at a nice overhand right. You have to be in position to land it, so you're well within punching distance. If you use the proper principles and mechanics of an overhand right, you can use it as a disguise to shoot for a double or single leg. It can be a nice little cheat to get at his lower body.
Likewise, on the ground, if you have someone in your closed guard, using your core and hips to hold them, or move them to slightly different distances, or slightly left or right, you can utilize your punching, or elbows, with pretty much the same torquing principles as you would standing up. Your base would be different, but your core rotation would follow the same principles, albeit, not as strongly.
