This is very interesting: I'm going to link your post in my timeline, so that everyone can read it.
There are useful hints to build the timeline, but you still have ROTJ's rectons like Owen being Obi-wan's brother (George... :\) and so Obi-wan being only in his 60s (which contradicts Tarkin's statement).
I'm not sure it can be actually used, but it's definitely a great read. Thanks a lot!
