There has been some earlier investigation on this. The structure on the triangular points is indicative of what is called an Eastern Crown. Other historical examples use different ornamentation.

There is no such issue here.  That crown was definitely added by the last Retracer on blank vellum.

What I meant was that maybe the paint makes us have a different interpretation of what was meant in places. (maybe misleading us the viewer, rather than whoever did the ink)
For example if the person just decided to paint a dress red, the solid red (caused by crude paint) makes us think of a thick materials. 
Or maybe a better example is blue blocks next to blocks with stars, one interpretation could be that the blue is the sky, another might be it is the sea.. or others, but really we can;t tell much but "blue" because of the crude nature of the application. 

But yeah, I'd agree the paint looks like the final step in completing an image in the MS.

Looking at the 'headgear' in Post #8 as it was drawn on the page, there are two apparent facts. It is an Eastern crown with pointed palisades and it has the imperial 'basket' on top. So, name an eastern empire relevant to the C-14 dates. The Holy Roman Empire. Then name a woman who was an empress during that era. First on the list still seems to be Barbara of Cilli.

The medieval illustrations of Barbara of Cilli show her with a different style of crown; one where the palisades are shaped like three-leafed clover or the upper stem part of a heraldic cross botany. The problem with this version of a crown is that it was more widely used, like the fleur-de-lis, and if used in the VMs, would seem to be less accurate in designating a specific person as an HRE empress.

Nymphs in the VMs may be identified by their attributes, be it a cosmic spindle or a green dress - as long as we can identify their attributes.

I think, as per my earlier post, trying to find a person is probably several leaps of faith too many. Along with supposing "female". 
But likely the style of crown can be placed. I have a pretty ok candidate. 

To me, the general vibe is - You are not allowed to view links. Register or Login to view.
The features it shows depict the import/rank of the person, as you can see on the wiki the addition of the top part has a correlation with rank in many different European countries. 

I'm working on a time-line for a possible candidate, I'll post a thread when I've had time to do it properly. If others want to chip in (with other decent candidates) we might be able to draw some times, hopefully at least "from" can be agreed on for the overall style.

   

I see it differently.
If there was a tracing, then there was also a preliminary sketch. This can be seen from the double zigzags (marked). In terms of colour, it was sketched in pencil (double lines). Ergo, it already had a crown before the tracing.
The crown is typical of the Habsburgs. This applies to all three crowns.
