That’s an interesting idea. I’m not sure that LACNIC would want to issue a ROA for RIPE IP space after RIPE issues an 
AS0 ROA, though. And you’d at least need some kind of time delay to give other RIRs and operators and chance to discuss 
the matter before allowing RIPE to issue the AS0 ROA, eg in my example mitigation strategy.
