The only way to do it is to change encroachment (dead ball) to offsides (live ball). I would support that change.
Fed seems awfully proud of their blow-and-throw DOF. It sounds like that's never gonna change.
BUT. Another workaround could be:
Let all dead-ball fouls during a try (i.e. after the RFP)
be enforceable on the succeeding kickoff, at the option of the offended team.It's symmetric to both teams (which Fed likes to see when possible) and it doesn't require that much retooling of the rulebook since this is how dead-ball fouls after a try, plus live-ball fouls during a successful try, are already treated.
(p.s. as to how this would work at the end of the 4th quarter or in overtime, I dunno, call that TBD, I'm just giving the elevator pitch here)
