Dark Agartha Free Elaborate Glyph Imbuer

I would like to know, if can change my free Elaborate Glyph Imbuer (soulbound) with the Imbuer-Exchanger from the Dark Agartha Vendor (the one for 500 Aurum) into a talisman imbuer.
I don’t want to waste 500 aurum if it doesn’t work.

Good question.

I believe those are stated to only work with tradeable items.
