I don't believe this is possible. Law 21.4 requires that those players ahead of the penalty taker should retire, and the sanction for all failures of this law is given at the end; it is a scrum at the mark of the PK.Or, if you have called him back, and he has ignored you and has been very material in the effect on the game, then why not a penalty for offside? And possibly a card.
It says: "Unless otherwise stated in Law...", so I think there is a legitimate argument that Law 11 applies.I don't believe this is possible.

I wouldn't reach for the whistle but allow play to continue, indicating scrum advantage to black. Tell green offside player to retire. Wait to see if advantage is gained by black, scrum back if not. If the Green offside player fails to retire and prevents black from gaining advantage, penalty to black with option of where to take the penalty.
(First post - waiting to be hammered! LOL!)
Note I was talking about a situation where the player has refused attempts at managemenht and has had a material effect.
I see no reason a PK should not follow - the scrum would be the standard option, but you can escalate it if required.
