Okay, this is confusing. So...
First of all, the Galleon Trade only happened because Spain already controlled a route going from Europe to Asia from the Americas. It came full force in the 17th century, even as the Dutch pirates made it increasingly difficult to trade.
Second, the Majapahit Empire, such as it was, barely controlled Sulu at its height, being a very regional player, not sending out expeditions where they knew there was nothing but wilderness. By the time the Galleon Trade even started, they had long passed into the dust of history, crushed underfoot by the rising Muslim sultanates.
Third, the Pacific is big, and there is no incentive for anyone to send out expeditions to what is practically the middle of nowhere. The Europeans knew the world was round and wanted to get to China without dealing with Muslims or worse, Venetians. The Majapahit have no comparable desire, save perhaps to escape the fall and the Muslim sultanates. Which is why they came here.
All this makes it impossible for the Majapahit as we know them to go across the ocean and meet the Aztecs and Incas as we know them, let alone start a large-scale trading network across an impossibly vast ocean (to them) for resources the Majapahit already have.
