"#5 is the safest, but my least favorite mostly because of the lid. Can't get over it. It just doesn't belong in the OK and the MK and later did not make them out of stone that way regardless. It is more plausible to me the lid was actually like Meresankh III's or was like other lids of the time which given the uncertainty of the pieces Vyse found they inverted it in their recreation based on later MK sarcophagi they had seen unaware this style did not exist in the OK.
Interesting that EoH would bring up Khaemwaset (NK) who apparently took an interest in restoring sites from the OK including Giza. Egyptologists believe it was he who inscribed Menkaure's name on the entrance (of the temple I believe and not the pyramid, but I could be wrong) so maybe it was Khaemwaset who restored Menkaure's sarcophagus by painting the border pattern and installing a new lid of a style common to his time. We also know there was an intrusive burial there regardless of when and given tomb robbers would a have smashed and grabbed what they could it is logical by the time of this burial the lid would have been removed and damaged necessitating the need of a new lid made in a style of the time."
It's possible that the lid was replaced at a much later date, and could've been Khaemwaset's work. And possibly the tomb-robbers re-entered after the lid was replaced, and smashed the replacement lid. (It might be worth a trip to the BM to see what they do have. I'd be glad to go, but I'm too far away.)
I agree, Vyse's reason for the sarcophagus' removal is a bit thin.
My earlier point on the minor differences in the 2 drawings come from my experiences w/ researching Djehutyhotep's Tomb in el-Bersheh. There were many drawings, but all had at least minor differences...so I finally checked the actual tomb painting. It could've been simply the result of human error.
I'm not 100% sure that these drawings do represent an actual building as this style of facade could've been adopted somewhere along the way.
(And I don't have any ideas on how to follow up on this.)
