K Tack-On enforcement in unusual cases

[Morningrise]

10-4-2 says any K foul before the end of the kick, except KCI, can be tacked on at the succeeding spot, as long as R would put the ball in play next.

Naturally, I started thinking up some unusual ways that this condition could be true. Can K's foul still get tacked on in these two situations?

1. Team K trails by 3 points late in the 4th quarter. K1's field goal attempt is tipped and rolls down the field. R55 picks up the ball at the R-4 and retreats (no momentum) into his end zone where he is tackled. The clock reads 0:02. Prior to the kick, K88 committed a personal foul at the line of scrimmage. Team R's coach says, "We'll concede the safety, but we want to free-kick from the 35, not the 20." Can they?

2. 2nd and 10 at the R-35. Team K is attempting a trick play at the end of the 2nd quarter. Quarterback K11 receives the snap and pitches the ball forward to split end K88, running an end-around. K88 then tosses the ball to K11, but this pass is also forward. Seeing that the play is a failure, K11 punts the ball. The kick rolls out of bounds at the R-4. Time expires in the 2nd quarter during the down. Team K had won the opening coin toss and had deferred. Team R's coach says, "That's an illegal forward pass by the kicking team. Loss of down, so the quarter is not extended. If they elect to receive the 2nd half kickoff, we get to kick off from the 45, not the 40." Is that right?

I'll give it a shot.
   1. Yes. The result of the play is a safety. R will be next to put the ball in play by free kick. They can take the succeeding spot enforcement.
 2. No. While it's possible R may be the next to put the ball in play, it's not guaranteed. Whether R accepts the penalty or not is irrelevant because the half is over. If R does accept the penalty we have to go back to SPOT OF FOUL, (oops) mark off 5 and it's K's ball 3rd down. But they can't run a play

1. No. A Safety negates any live ball foul enforcement on the previous play. Live ball or Succeeding Spot Carryover Fouls only occur on Touchdowns and a Try, & Since K is putting the ball back in play on the next play this tack on rule does not apply.  6-1-1b, 8-2-2 & 3, 8-3-5, 8-5-4, & 10-4-2.
2. No. We are kicking from the 40. The foul, if accepted, results in a loss of down with no time left. By rule the half is over.

I tend to agree with you on #1, particularly because R will not be the next to put the ball in play. If we are strictly talking about team designations and not considering "R" as a particular team, 6-1-1b would definitely apply.  However, I have some issues with the otherrule references.
8-2-2 & 3 refer to fouls by the opponents of the scoring team. This situation is a foul by the scoring team.
8-5-5 does not apply because the foul was during the down, not after the down.
10-4-2 does apply.
So, R would have to decline K's foul to keep the results of the play. If they accept the foul, we go back to previous spot and mark it off.
