YES, why has no one else thought of that in this case Maul is resurrected as a cyborg (not totally unlike in the clone wars except without the robotic legs) so it wouldn’t make sense if he was collecting jedi lightsabers since he’s a sith he just has his own plus he always had a double bladed sabre, so he’s used to wielding more than one blade, to make use of his extra arms he just decided to wield 4 single bladed ones and ditch his old design to better fit his new enhanced skills as a cyborg
