Aesthetics - dyes and glamours

Will we ever be given the opportunity to dye older undyeable gear (coil, tower, etc.)?

Will we be able to wear/glamour face and head items seperately? There are players who would like to wear glasses, mask, mustaches and such with their hats. Npc characters such as Ahldskyf (Limsa Lominsa Lower decks, (9,11)) can, so why cant we ?

Will the glamour system ever be updated to remove certain restrictions?

When augmenting certain peices of gear, the primary color (dyeable) is actually the better suited color to remain. The choice of secondary color (teel on the Ironworks bard feet) remains, which limits/clashes with dye options and makes certain items unsuitable for glamours or pointless to dye. Can some consideration be given to the primary and secondary colors in the future?
