We are working to change currencies to be Legacy based. This includes unassembled components, credits, the Umbara currency, and more. I'm not aware of any major obstacles preventing this from happening, and doing so will help with a number of changes we are planning for the future.
I know that doesn't solve the concern about having to run the Flashpoint multiple times on one character, but once you have the Key to open the Stronghold, you can use the currency for other items on the vendor.
Have a good weekend,
