I think HSOTD would be best cos it will shorter arc after a long one. And he could do a crossover for the arc after which I think would be good. like a DBZ mass effect crossover where the milky way galaxy is protected by the reapers while the frost demons like frieza and his family rule most parts of the universe with the galactic patrol kind of defending the rest. the reincarnator could be a Saiyan whose around early DB Goku strength and the average strength for the ME characters are early DB levels like the red ribbon army lot. and the androids could be made by Dr.Girou alongside Cerberus to fight the reapers but not be ready until a few years after they are destroyed. so when they reincarnator ends up destroying the reapers alongside Sheppard the galaxy opens itself up to an attack. the sayain saga can start within a year with raditz coming. the the other sayains alongside frieza force and eventually the namek saga and when this is all done the androids are made and upgraded. for example cell would have the DNA of the main DBZ lot like originally alongside frieza,ME races and other stuff.
