Guild Wars 2

The Tempered Spinal Blades, both infused and not, require quite a bit of materials in order to make and it seems silly to go through the whole process again if one wanted to just change the colour. With the event passed, its exceedingly costly to get the materials required to remake it especially to change the colour as a player has decided to change their attire and want a backpiece to support it.

I was wondering if perhaps, instead of having players repeat the process again, maybe there could be something in the gem store for say, 200/400 gems, for each of the colours, that allowed players to change the colour of their Tempered Spinal Blades.

As an example: At the moment, for an Infused Tempered Spinal Blade backpiece, you need to have the Tempered Spinal Blades, Power Core, Gift of Ascension and Glob of Coagulated Mists Essence.
The player could buy the colour item off the gem store and use that in place of the Power Cores, as well as substituting their Infused Tempered Spinal Blade into the Tempered Spinal Blade slot when using the Mystic Fountain, and then the result would be the coloured backpiece corresponding to the item they bought off the gem store!
