Okay if my posted created 2.5 I will try again to do your Version 2:

§ 37 [On a time when Eärendil was yet young, and the days of Gondolin were full of joy and peace {and yet Idril's heart misgave her, and foreboding crept upon her spirit like a cloud}, Maeglin was lost. Now Maeglin loved mining and quarrying after metals above other craft; and he was master and leader of the Elves who worked in the mountains distant from the city, seeking for metals for their smithying of things both of peace and war. But often Maeglin went with few of his folk beyond the leaguer of the hills, though the king knew not that his bidding was defied; and so it came to pass, as fate willed, that Maeglin] {Now it so chanced that not long after Maeglin went to the hills for the getting of ore, and} straying in the mountains alone was taken [prisoner] by some of the Orcs prowling there, and they would do him evil and terrible hurt{, knowing him to be a man of the Gondolindrim}. This was however unknown of Tuor's watchers. [Maeglin was no weakling or craven, but the torment wherewith he was threatened cowed his soul, and] {But} evil came into the heart of Maeglin, and he said to his captors: "Know then that I am Maeglin son of Eöl who had to wife Aredhel sister of Turgon king of the Gondolindrim." But they said: "What is that to us?" And Maeglin answered: "Much is it to you; for if you slay me, be it speedy or slow, ye will lose great tidings concerning the city of Gondolin that your master would rejoice to hear." Then the Orcs stayed their hands, and said they would give him life if the matters he opened to them seemed to merit that; and Maeglin told them {of all the fashion of that plain and city, of its walls and their height and thickness, and the valour of its gates; }of the host of men at arms who now obeyed Turgon{ he spake}, and the countless hoard of weapons gathered for their equipment{, of the engines of war and the venomous fires}.

§ 38 Then the Orcs were wroth, and having heard these matters were yet for slaying him there and then as one who impudently enlarged the power of his miserable folk to the mockery of the great might and puissance of Morgoth; but Maeglin catching at a straw said: "Think ye not that ye would rather pleasure your master if ye bore to his feet so noble a captive, that he might hear my tidings of himself and judge of their verity?"

§ 39 Now this seemed good to the Orcs, and they returned from the mountains about Gondolin to the Hills of Iron and the dark halls of Morgoth; thither they haled Maeglin with them, and now was he in a sore dread. ...

In this version Meaglin tells only things that are to be expected for a community of Elves in such a situation as Gondolin was in. So what he told to the orks would not be of any value to Morgoth. Did the Gondolindrim know that Morgoth searched for Gondolin in special? If not we can imagin Maeglin to try and tell the orcs not to search further beause they would be in danger near to the city and to let him go because the Gondolindrim would search for him and find them. In addition he had in this Version not even told the place of Gondolin to the Orcs, so he might hope, to win his life with this information from Morgoth.

Your version 3 is also easly done so her it goes:

§ 37 [On a time when Eärendil was yet young, and the days of Gondolin were full of joy and peace {and yet Idril's heart misgave her, and foreboding crept upon her spirit like a cloud}, Maeglin was lost. Now Maeglin loved mining and quarrying after metals above other craft; and he was master and leader of the Elves who worked in the mountains distant from the city, seeking for metals for their smithying of things both of peace and war. But often Maeglin went with few of his folk beyond the leaguer of the hills, though the king knew not that his bidding was defied; and so it came to pass, as fate willed, that Maeglin] {Now it so chanced that not long after Maeglin went to the hills for the getting of ore, and} straying in the mountains alone was taken [prisoner] by some of the Orcs prowling there, {and they would do ... this seemed good to the Orcs,} and they returned from the mountains about Gondolin to the Hills of Iron and the dark halls of Morgoth; thither they haled Maeglin with them, and now was he in a sore dread. ...

But as Meadhros, I am very interested to see how you would deal with your Version 4.
