Here's the thing:
While you have some great and interesting ideas, there are two fundamental flaws with them.
1) They are totally impractical. As has been said, you cannot edit canon at will to such a great extent. A massive Empire could never have existed alongside the Republic or Empire without any mention of it being made. Likewise, multiple invasions of the scale you describe would never have been simply "forgotten".
Han Solo, as has been said, is Corellian, and you cannot simply change his ancestry to suit your story. We do not (generally) change the stories of major canon characters for our own ends. This is not to say you cannot use canon characters, but they are few and far between, and are nearly always roleplayed (only as necessary) by experienced, veteran roleplayers - not rookies. The reasons for this should be obvious.
Simply put, there is no feasible way to work the history you've described into the Star Wars canon.
For a description of canon,

Aside from the historical impossibility of the events you've described, there's also a very real problem with the liklihood of them happening. Your Empire could have "easily crushed" the New Order, and they hate the New Order, but instead they decided to voluntarily shrink and do nothing about TNO?
Unlikely, to say the least. Your history needs some serious rethinking just to fit into the SW universe, never mind the TRF galaxy (which leads me to my next point).
2) They do not fit into the TRF continuity. We are currently set ~45 years after
Revenge of the Sith. Our history begins roughly where the
[url="http://starwars.wikia.com/wiki/Black_Fleet_Crisis"]Black Fleet Crisis[/url] ends off.
Simply put, you cannot insert a major galactic Empire into the midst of this time line and say "no one ever noticed it". It does not work, for a number of reasons I will not get into. Suffice to say, it is impossible.
For more information on the history of the TRF galaxy, see our

It also does not fit in with the
[url="http://therebelfaction.com/forums/faq.php?"]rules[/url] of our community. You should read over all of them carefully before going any further, but make a note of
[url="http://therebelfaction.com/forums/faq.php?faq=therules#faq_rules_charactersandgroups"]this one[/url]:
Groups can own planets. A group can own (or control) an unlimited amount of planets. Planets are captured by writing a role-play of at least 5000 words and then posting in the Planets List to claim said planet. Planets give Groups Assets (see below) that can be used in various methods.
You see, if you wish to start a group called 'The Great Atlantean Empire, you can do so. But in order for it to be an Empire spanning worlds on TRF, you have to develop it on TRF. You need to write 5000 words for each planet in your Empire (though you can say that planets are within your 'sphere of influence', this is not quite the same, as power is measured in part by the number of planets you own, as opposed to influence).
You should also keep in mind [url="http://therebelfaction.com/forums/faq.php?faq=therules#faq_rules_assetquantities"]this rule[/url]:
It should also be noted that the days of massive fleets consisting of hundreds and hundreds of ships is long gone. In your writing remember that building a single Star Destroyer could very easily drain the entire resources of a single planet, or system even.
So having multiple, 25-kilometre ships, is a big no-no.
If you have any other questions, there are plenty here that would be happy to answer them. Just ask, and don't assume things.
And read the rules carefully and make sure you understand them. If you don't, ask!
