Take all that talent and knowledge from both OSes and create a new Amiga compatible and "Amiga like" OS that is a step into the future for everyone.
I see a small problem here, assuming Amiga Inc wins (and I can't see how they could lose really), it means that they would pursue any attempt to re-use the knowledge gained from working with the AmigaOS 4.0 (it is based on the original sources after all), meaning anyone in the team would be tainted forever.
So assuming such project would ever be started (note: this is speculation, I am
not signing up to any such project here), it'd be quite impossible to include anyone from the OS4 team, just alone because of this.
BTW I don't find this funny, only slightly ironic.
