How would you Fix the Less Popular HOTS maps?

In HOTS there are several maps that have kind of fallen to the sidelines in terms of popularity for varies reasons, some are no longer in the rotation, some you can't play in ranked. What ways would you change these maps for the better?

I would change Haunted Mines by making the objective be about structure armour instead, kind of like how the 'cores' on Alterac Pass get armour based on how many of the keeps remain.
While the mines are open I'd add some armour to all structures and when all the skulls are collected the amount of armour or vulnerability to your structures would be based on the percentage of skulls you collected. Maybe to make the numbers easy start with 20 vulnerability and add 1 armour for every 2 skulls, so that you could get 30 armour if you collect all of them, or if each team gets 50 skulls each team has 5 armour on their buildings. The armour or vulnerability to your structures would end when the attacking golem dies.

Aren't they all "less popular" at this point?

Nah these are the ones that are frequently brought up in the conversation of either taking out of ranked or never putting back in ranked. And historically ones that have design or balance flaws people frequently comment on
