Is it at all possible to get Prophecies armor sets in diffrent insignias?

Like for example I want Frostbound armor but with Druid's inisgnia?

Thanks,

factions did offer some of the original ascalon style armors with different 'insignias' but for the 15k ascalon type armors, not really. And you cant change the 'insignias' when you like either---that is only on elonian armors.
If you have a specific armor in mind check out guildwiki's armor sections and you can look up the differences (and similarities) for all the armor in the game.
hope this helps.

No, different looks in prophecies armor have different properties. In factions, the same looking armor can have different properties based on what you choose when you buy it. In nightfall, you can upgrade the different armors with any insignias after buying.

I wish you could, but the answer's no.

I think Obsidian, (FOW), armour is the only exception available in prophecies
