In all seriousness, making such a "petition" is not a good idea because they can just say Murfy is vital to game experience and dismiss it. Even then, this game is launch window exclusive, which basically means porting it will probably result in seizures, as it's a mess. And then it's highly probable that Nintendo paid for RL being an exclusive there. And then even if those didn't exist, Origins could have dramatic differences in sales on various platforms.
If you actually want a serious petition, get friends, then write simple, yet precise declaration of RL porting having any remote sense. Then UbiSoft could care for it - if it gets signed enough, which is actually quite problematic; after RRR, number of people highly interested in Rayman decreased.
