Will Grievous Lady and Fracture Ray get a Beyond or Eternal Chart?

This is just a random thought after seeing Axium get a Beyond Difficulty. It makes me wonder if they would get a Beyond or an Eternal Difficulty considering they pale in comparison to the charts of newer boss songs and the fact that Axium got her revenge after being downgraded to a 10.

I would love to hear your opinion. Are they worthy for an upgrade or are they perfectly fine as they are.
