I think that an interesting remodel for Pallada is the Aurora!
In real life, the Aurura was the same as the Pallada until it's 1915 remake, where it exchanged most of it's smaller guns for 6 more main guns.
So it went from 8x152mm and 24x75mm and 8x37mm to 14x152mm and 4x76mm. So I think that in NF, the Aurora can lose alot of it's AA but get's 4 more main guns. Which would be an interesting combination.
As well, the Aurora has some interesting history to go with it (just like the Hood).
