^According to Miyamoto, which you seem to love director quotes, LA had no real place in the timeline.
Give me all of your proof for LttP-LA. Just so I can know why you believe LttP-LA.
"Link, who had defeated the evil Ganon and regained peace in Hyrule, had not enjoyed the archived tranquility for long, and eventually becomes restless. Feeling in need of training or enlightenment, he embarks on a journey and sails across oceans in a small sail boat."
in OoX, Link fights Ganon in Labrynna/Holodrum, not in Hyrule. the BS for LA states that after defeating Ganon he brought peace back to Hyrule, which implies that Ganon was defeated in Hyrule, not in Labrynna/Holodrum.
also, it says after training in foreign countries, not after 2 massive adventures in foreign countries, he set sail back to Hyrule. he defeats Ganon at the end of ALTTP which would make sense to lead into him leaving Hyrule after saving it. now if you are correct and OoX is the prequel, that means that there is the same link in 4 different games...the most adventures any one link has gone on in the series is 2. i would think the creators would move on and give a new link a new adventure before they decided to make 2 more adventures for a link that already had 2 adventures.
based on your timeline theory of this, Link deafeated Ganon in ALTTP, then defeated Ganon in OoX (which means he defeated him twice) which means he defeated Ganon 3 times in one lifetime. then in LA he defeates a nightmare Ganon and Aghanim (who is ONLY in ALTTP). thats a lot for ONE link to do.
