Well, sure, it takes away thought if you make that permanently part of their persona.
If they became that way for a mini-series of, say, three issues, then it'd just be a fun little foray from the norm. Doesn't even have to be canon (and actually, I'd prefer if it wasn't).
It'd just be fun and interesting to see.
And yes, of course I put a lot of thought into it. This is The Penultimate you're talking to. In my mind, Waldo and Carmen Sandiego make for among the most awesome and kick-butt anti-hero team in the world, and basically every fictional protagonist/antihero in the universe come to Planet Celadon to party at a moment's notice.
