The conventional chronology puts Ramases II in the 1200’s BC. Eight hundred years later would put him in the time of the great Persian kings, and I think history would have a lot more to say about the clash of two such great kingdoms. I’ll stick with the conventional chronology, give or take a hundred year, at least for the Eighteenth Dynasty. I know that further back various “experts” have disagreed by as much as 600 years on the Old Kingdom rulers.
Then there’s no point to looking for Moses (or David, or Solomon, etc) because there are no synchronisms. And that lack is the reason the pseudochronology was concocted in the first place.
