I agree with your points about the similarites between Alttp lost woods and the ruins in TP. It is something that i have noticed as well and i have examined and noticed that the ruins in the sacred grove in TP, if the same place seems to be more constructed and hidden within the thickness of the woods in Alttp.

However i dont agree with the Temple of time being the portal/gateway to Termina.
First i dont think the sacred realm as anythin to do with Termina. They are two completely different places and i dont see how because the temple of time links Hyrule to the sacred realm it would link it to Termina as well.
Also its a big assumption to say that the woods Link parted from when he left Hyrule was even near the temple of time.
It seems more likely that its the lost woods and would also explain how Skull kid managed to get into Termina.
