Lets put this into context, The Mongols over ran India But could not conquer South East Asia.
So if an Empire much more powerful then India couldnt conquer South East Asia, what would make you think a weaker Indian Kingdom do it?
What are you talking about? The Mongols never conquered India either. The Delhi Sultanate had successfully repelled a number of Mongol invasions. If you are referring to the much later Mughal dynasty though, that really has nothing to do with the Mongols, besides its founder Babur being a distant descendent of Chingis Khan. That doesn't really mean anything though, as Babur was mainly a Turk raised in a Persian culture with an army mostly consisting of Indians and Afghans. And he wasn't the one who expanded the Mughal Empire across India either, but it was his mostly Rajput descendants who did that for him.
As a matter of fact, one South Indian kingdom, the Chola Empire, did successfully conquer large parts of Southeast Asia (namely the western islands of the Malay Archipelago and the coastal regions of Indochina), though the occupation only lasted for several decades at most before the Chola army suddenly left. I think the purpose of the invasion was probably just to exact tribute though (or maybe just plunder) rather than conquest.

im skeptical as well, but there just is no way to know if Mauryan could conquer SEA back in 200 BC.
The thing about the Maurya Empire is that, although it was already very large (consisting of modern India, Pakistan, Bangladesh, Nepal, Afghanistan and eastern Iran), it could have expanded even more than that if Ashoka the Great didn't suddenly have a change of heart after his conquest of the Kalinga kingdom. After seeing the large number of civilian casualties he was responsible for, he wanted to change his ways by adopting Buddhism and taking an anti-war stance. Instead of conquest, his new mission became the transmission of Buddhism across the world, by sending missionaries south to Sri Lanka, east to Southeast Asia, north to China, and west to the Hellenistic kingdoms.
There is indeed no way of knowing what would have happened if Ashoka didn't have this change of heart and instead retained his previous 'conquerer' mindset. Maybe he would have eventually clashed with the Hellenistic kingdoms to the west or even invaded Southeast Asia to the east? Buddhism probably wouldn't have become a major worldwide religion either if Ashoka didn't send all those missionaries across the known world.
