No. Sanity lets you plan ahead and not do fucking stupid shit that gets you killed because you're a nutjob who didn't think to take into account perfectly sensible and blatantly obvious things that any normal person would have thought of. When you're "good and crazy", you miss things, react illogically and in dumb ways to events around you because your brain isn't working right, and wind up making simple, easy-to-correct mistakes and getting splattered.
Sorry, but Imago goes for verisimilitude and realism. And in the real world, "being crazy" isn't a superpower that lets you outmanoeuvre all those pesky people who are limited by their "sanity" and "logic" and "rational, evidence-based planning that has contingency measures for what to do if the plan goes off the rails". The universe will not play along with your delusions because you see things in a way that's more speshuler than puny pathetic sanity. You're just mentally ill, a state which is rarely conducive to competency, and the universe will roll over you and crush you beneath its tracks because it does not give a shit about you, and the nice logical sane people understand how it actually works, and you don't.
And frankly, "leave sanity behind and you can be much more effective!" is just fairly blatant and incredibly boring anti-intellectualism, which tries to cast learning, knowledge, logic and rationality as "bad things", and delusion, superstition, irrationality and chaos as "good things". Which is fucking stupid.
