Given that Amiga Corporation stated the settlement involved offering 3.2 "for free", I can see why you choose the word "unlikely". heh.
While there is little hope of "financial remuneration" for further developing free AmigaOS components, competing against components which are free may not be very lucrative either, at least where there is development overlap and regular updates. The contingency plan logic makes some sense though, especially considering the lack of development for AmigaOS 4 and the legal mess.
