Although it'd be poetic justice & would force the general public into awareness of the fraud at play, we have to assume anything which happens must be of service to the new company - they won't just give away equity as a gesture of goodwill. A credit bid or legal decree could catalyze a chain reaction which leads to a black swan event, but anything outside of "business justification" or precedent will present a legal (or legislative) liability; IE, a loophole to shutdown the ensuing madness.
The ongoing fraud investigation presents a massive "undo" button for this entire mess, though. If fraud is determined to be a cause of BBBY's bankruptcy then something vaguely resembling what you describe is possible. Until then, I'd assume redemption would only come in the format of a credit bid or legal settlement, because as of now BBBY/Q shares are extinguished & dk-butterfly is a legal entity of the bankruptcy process.
Everything is speculation & we simply don't have all the info yet - there are too many positive indications, unanswered questions & seemingly nonsensical factors for this NOT to be significant. Hell, it appears even the big boys like JPM & whoever has Gasparino by the sack is clouded in confusion too. Those who know are battling major players and likely have obfuscated as much as possible, deployed red herrings, and proxied tactical elements through multiple layers - one mis-step and their play may be in jeopardy. All we need to do is relax, not get too invested in one particular theory (of many), and let the titans battle this out.
