"Is it possible?" Sure, why not. But possible doesn't mean likely.

There's absolutely no way for a historian to answer what if questions. I've seen it best explained through an example of going to the grocery store.

Say you need groceries, you realise this at 7 o clock at night after getting home from a long day at work. You've got enough to last you til tomorrow, but not ideally. You could go to the store tonight, or you could wait until tomorrow. It's a scenario every adult has experienced.

So what happens if you go tonight, versus going tomorrow? In 99.9999% of the scenarios there's absolutely no difference maybe other than a bit of annoyance. But, for those small chances there are people that go out and get in a life changing car accident, or get food poisoning from stock that would have been replaced overnight, or run into an ex, or meet the person of their dreams in the queue, or a million different highly unlikely but entirely possible scenarios.

If you play that game for just ONE person it's highly unlikely that anything will change. But if you play that game with an entire population for hundreds of years, you're going to hit a lot of crazy odds.

So when we play the game of "what would happen if this entire group of people and this entire group of people combined with this entire group of people matched up differently..." we get into an absolutely unimaginable amount of scenarios and probabilities. Expand that over many generations and it's even more so. What if one of those people who would have been a great leader never existed because their parent died, etc. etc.

It may be fun to imagine, but there's no academic way of answering it. There is /r/HistoryWhatIf where they have a bit more fun with this, but again, take every answer with a dumptruck of salt.
