Exchange old currency for new stuff

Hey
I think one of best updates was the one where we got chance to exchange seals (beastman/kindred/...) into other.

Well if we could get now chance to exchange currency (CP/Campaign points/Assault points/ Voidstones/Abyssea-Stones/....) into other stuff..........that would be great!

I have over 1k Voidstones and no use for. So if I could exchange 10 Voidstones for 1 Beastman seal or CP for Plasm or w/e to w/e then it would very nice.

I am sure i am not the only one who wish to exchange stuff for other stuff.

Also it would great if u guys could add sparks quest for old end game content e.g.:
quest for salvage (maybe Key item for a win => exchange all wins for 1 item)
quest for sky/sea NMs
quest for winning an assault/nyzul
