Availability of HMPs, Riftcinders, Riftdross

[Sapphires]

I came back from a multi-month break from the game and thankfully I had several hundred voidstones saved up.
When you put in the time to do the content, the drop rates are good for hmp/dross/cinder. There is constantly people doing VW during the campaign right now (even a bit of 'congestion')

Over the course of a week 3 players have been able to pool their drops from voidwatch to have half the heavy metal and cinder to make a new empyrean.
The biggest problem I have is voiddust is nonexistent, and there is no reasonably time efficient mechanism (by doing 119 content or capacity points farming, or a gil-sink) to create 6 voidstones.

The purveryor rates for converting AN/CP are pointless (who is going to use copper 2 vouchers for the AN/CP to get just 1 dust).

Can you please have the Curio Vendor Moogle sell voiddust for 6-9k gil each?, that way people that love doing voidwatch have a means to do the content and not be time gated so heavily?
I want to stay subscribed and farm for more empyreans, i'm ok with a gil cost that allows me to repeatedly to do the content (for the economy balance) so I could do it repeatedly like dynamis/salvage can be done these days.
