Has Christopher Tolkien said how he would have done "On the Ruin of Doriath" differently?

Question

The chapter On the Ruin of Doriath in The Silmarillion is known to have been a rather extensive synthesis by CJRT of JRRT's existing texts (plus a bit of his own creativity), which were less cohesive/inter-consistent than and with the other parts of the Quenta Silmarillion that was being assembled. There are sources and discussions here and here. Key quote (emphasis added):

This story was not lightly or easily conceived, but was the outcome of long experimentation among alternative conceptions. In this work Guy Kay took a major part, and the chapter that I finally wrote owes much to my discussions with him. It is, and was, obvious that a step was being taken of a different order from any other ‘manipulation’ of my father’s own writing in the course of the book: even in the case of the story of The Fall of Gondolin, to which my father had never returned, something could be contrived without introducing radical changes in the narrative. It seemed at that time that there were elements inherent in the story of the Ruin of Doriath as it stood that were radically incompatible with ‘The Silmarillion’ as projected, and that there was here an inescapable choice: either to abandon that conception, or else to alter the story. I think now that this was a mistaken view, and that the undoubted difficulties could have been, and should have been, surmounted without so far overstepping the bounds of the editorial function. (from: HoME XI: The War of the Jewels: "The Tale of Years")

The big question is, has CJRT ever indicated how he would have "surmounted" the "undoubted difficulties"? He discusses the various difficulties immediately prior to this passage (quoted in the second posting at this thread), but I haven't read much of the History of Middle-earth, and haven't seen any quotes around the internet of what he might have proposed.

Answer 1

This is not really answering the question as stated, but it is in some sense even better: it's what JRR Tolkien stated was the solution to the problem, in a manuscript Christopher Tolkien apparently never had access to!

In Concerning ... 'The Hoard', a privately-owned 1964 manuscript recently put up for sale, Tolkien wrote that the Girdle of Melian was down either because it was robbed of its power to keep out evil because of evil deeds done within (the slaughter of Húrin's band of outlaws by Thingol's soldiers/guards), or because of Melian's grief and horror at this, she let it down herself. Then when the Dwarf army turned up after Thingol reneged on paying for the Nauglamir/Silmaril fusion job (he isn't killed immediately, in this version, contra Christopher's 1977 edition of The Silmarillion), they could easily enter Doriath, and Thingol and most of his army was killed.

The Dwarves were angered, all the more because they had themselves come under the dragon-spell. They rejected Thingol’s terms, and refused anything less than the full tithe of the treasure of Nargothrond. Unpaid they departed in wrath. Back in their mountain-strongholds, they plotted revenge, and not long after they came down with a great force and invaded Doriath. This had before been impossible, because of the Girdle of Melian, an invisible fence maintained by her power and will through which no one with evil intent could pass. But either this fence had been robbed of its power by the evil within, or Melian had removed it in grief and horror at the deed that had been done. The Dwarf-host entered Doriath and most of Thingol’s warriors perished. His halls were violated and he himself slain.

The story then progresses much as before, this access to Doriath being the crux of Christopher's problem.

Answer 2

With the passing of CJRT, I believe the answer will now have to be 'no'. I left this open in case it was eventually addressed somewhere, but without a discovery of some very obscurely published commentary we can only surmise or infer from the existing HoME content.
