I took this into major consideration, and here are my opinions.
1. The Oracles feature the Master Sword as the max upgrade for Link's sword, this and this bit...
2. Link and Zelda don't know each other, and even though you can say this about pretty much any game, it's possible that this Zelda is ST Zelda's daughter, and Tetra's great-granddaughter. Now, ST Link and Zelda are very close friends, so how about they get married? It fits in with your idea of a random Link traveling to Hyrule and being called on by the Triforce to go to the foreign worlds.
3. Link sailing away in the linked ending of OoX. This probably means he's sailing in the Great Sea, back to Hyrule.
Now I'm going to trail off into MY idea of the rest of the timeline. After this, Link gets married and has a kid, and the three of them live happily... Until Koume and Kotake come back, kill the OoX Link and Wife, leaving their boy, Link, to live on his own. But Kouma and Kotake then revive Ganondorf (again), and this time does not go after Link, but to the WW Castle, where he claims the Triforce of Power, flings the Triforce of Courage far away (but not TOO far :B ) and shatters the Triforce of Wisdom, shards of it landing around Hyrule. After this he changes into Ganon, the pig beast, and goes on a rampage, releasing monsters and turning Hyrule into a wasteland. Those who survived hid in caves with their remaining supplies. One day, Link sees a woman who turns out to be Impa, being attacked by monsters, and saves her. Impa explains Hyrule's situation, and Link agrees to rebuild the Triforce of Wisdom, kill Ganon, and save the Triforce of Power, and Princess Zelda. This is obviously LoZ. Then of course, AoL takes place, leading to the end of the Adult Timeline.
The biggest problem I see is two Hyrule Castles existing, for a time.

... Both support the idea of the Old Hyrule Castle resurfacing in the event of OoX taking place after WW.The Triforce was previously seen assembled at Hyrule Castle in TWW, and seems to disappear after being used to make a wish by the King, so it makes sense that it would be there.
