[Maédhros]

Now FG-TG-01 becomes:

But Turgon, who knew that Tuor, mortal as he was, had the favour of the Valar, marking his stout glance and the power of his voice sent to him and bade him dwell in Gondolin and be in his favour, and abide even within the royal halls if he would, <GA for Tuor was held in honour, for his kindreds sake>.

and FG-TG-02.5 now becomes:

Now Tuor learnt <TO [that] there was no queen of Gondolin[,]> <SF [for Elenwë Turgon's wife] perished in the crossing of the Ice; and Turgon was thereafter unappeasable in his enmity for Fëanor and his sons.> [This and] many [other] things [were] taught [to him] by Voronwë whom he loved, and who loved him exceeding greatly in return; or else was he instructed by the skilled men of the city and the wise men of the king. Wherefore he became a man far mightier than aforetime and wisdom was in his counsel; and many things became clear to him that were unclear before, and many things known that are still unknown to mortal Men. There he heard concerning that city of Gondolin and {how unstaying labour through ages of years had not sufficed to} its building and adornment {whereat folk travailed yet} FG-TG-02.5; of the delving of that hidden tunnel he heard, which the folk named the Way of Escape
This was to include the mention of why there was no Queen in Gondolin from UT: Later Tuor note 31. I think this keeps the meaning relatively intact while excising the outdated bits.
