First of all, if Duryodhan had won the war, I'm assuming that all the Pandavas - not just Bhima and Arjun - would have been dead at the end. Probably slain in battle. Along w/ all their sons.
Then the question would have arisen about the casualties on the Kaurava side. May not have been much: w/ Bheeshma, Drona, Kripa, Ashwatthama, Bhurishrava, Shalya, Bhagadatta, Jayadrath, Susharma, Alambusha around, assuming that Krishna didn't salvage the Pandavas w/ various stratagems on how to kill them, chances are that the Pandavas would have been done in within the first 10 days, w/o Karna even entering. W/o anybody from the Kaurava side, except perhaps Alambusha, dying.
If Duryodhan's descendant inherited the throne, I wonder what the occasion would have been to get to do the yagna to destroy the Nagas. But assuming that there did arise the occasion for Vyasa's disciples to narrate the story, I think the focus would have shifted as follows:
- Duryodhan being an ausara son to Dhritarashtra and Gandhari, as opposed to the Pandavas who were kshetrajya sons of Pandu
- Duryodhan becoming yuvraj of Hastinapur after the Pandavas disappeared in a fire in the house of lac
- Pandavas getting Indraprastha after marriage to Draupadi
- Pandava marriages to the daughter of Jarasandha and sister of Sishupala
- Pandavas losing Indraprastha in the game of dice, and being exiled to the forest (it may have edited out the vastraharan and other unsavory details)
- Then the 13 years would have focused more on Duryodhan's reign (which actually the citizens of Hastinapur fondly remember when Dhritarashtra retired to the forest), until the war
- May have covered Krishna's visit w/o the viraatroop
- May probably have left out the fact about Karna being born to Kunti (incidentally, if the Pandavas were gonna die, Indra would have known about it in advance, in which case, would he have bothered to deprive Karna of his kavach-kundalas?)
- Would have covered the war and the destruction of the Pandavas
- Duryodhan would have been coronated after the war, and his rule would have been covered
- All the kingdoms of Pandava allies - Panchala, Matsya, Mathura, Magadha, Chedi, Kekaya, Srinjaya, et al would have all gone to Duryodhan's brothers to start kingdoms of their own. Not sure where they'd have gotten 100 kingdoms
- Karna would have started a dynasty at Anga
- Gandhari wouldn't have cursed Krishna, but the rishis still would have, in which case, when Dwarka got destroyed, all the Yadavas would simply have drowned. It would have been more like the end of Ayodhya after Rama's reign, when everyone took jaal samadhi. There may or may not have been a fratricide
- Duryodhan and his brothers would have probably died of boredom
Hey you raised good points, but I meant that Duryodhan just somehow escaped to win at the last day and did put his son on the throne, the casualties remaining the same, with only expectation that all the Pandavas died by the last day. ..
Anyhow I don't think they could have completely ignored something as important as Vastraharan and the Lakshagriha conspiracy. Yes they could have focussed on the Pandavas failing to fulfill the Agyatwaas rule yet claiming for their return
