petition for prophecies/factions armor update

This is a petition for Anet to update all the existing armor and armor crafters throughout prophecies/factions armors to be able to have insignias added to them.(if not for everyone at least for all the accounts with nightfall added), if u read this and dont agree with it please leave an explanation,i'd just like to read why you think it's a bad idea.

I support this whole-heartedly, I have a few sets of armor I want to swap the bonuses of, without paying over 100k to do so.

Also: The +1 energy headpiece was not the kind I would have chosen! Boo that.

I have a little-tiny faith that this is something they'll eventually do - they eventually updated the sundering green items to 20/20 when sundering was buffed.

Only reason I can see they wouldn't: It would make certain armor types non-campaign specific, and is the only reason I can see they wouldn't do this? Overall I think the insignia's are an extremely, extremely good thing for the PvE side of the game, and hope to see it implemented backward... within a year or two.
