You probably better off buying another 2019 Mac Pro w/ 8TB SSD and selling your current one to offset, or some variation of swapping components. There's one avail for $3500 or BO.
AMD Radeon Pro 580X MPX Module. AMD Radeon Pro 580X. AMD Radeon Pro 580X 8GB. 192GB RAM - 8TB SSD. 8TB SSD storage. I can be renewed yearly if you want to.

Generally not a bad idea, although 6500$ is still a lot of money..
Maybe NAND exchange is an option for you:

The process is very similar to Intel-based Macs with onboard SSD.
I don't know if fitting NANDs are still available, perhaps
@dosdude1 can give reliable answers.
Sounds interesting, not that experienced with soldering though
Waste of money. Just get a PCIe card and add any NVME you want to it as a second drive. How are you filling all your PCIe slots?
Currently I have a Vega II and the Pegasus R4i, as well as a 4-port Sonnet USB 3.1 card. Oh and also a Radeon RX 6900 XT at the moment, so I currently have no space whatsoever to install PCIe SSDs.
I would not recommend purchasing a used Mac Pro from the US. ebay charges the VAT, but fail to register the payment correctly. So we end up having to pay the VAT again, when it arrives at the national customs.
EU made changes to the iOSS digital system, when Trump launched the tariffs last year. So it has been a complete mess, ever since. 🙁
This is an issue that even cause problems in Norway, and it was reported on a news site.
Not to get too political, but ever since the Trump administration has been in charge, international shipping / buying from and to the US has been an absolute nightmare. Really annoying and also pointless to be honest, a lot of sellers on eBay don't even ship outside the US anymore for these reasons.
So they still have them, interesting.
I do recommend to get PCI-E card and NVME storage.
This would be interesting if it were possible to do, but as with most things, Apple made the simplest things frustratingly difficult and silly. It's like they thought back in the old days, let's make sure we design the machine with the ultimate potential to upgrade be almost useless (no GPUs newer than ancient 6800/6900 series and hard to find bespoke storage).
Yes, I had a chat with him and it is quite interesting, you can buy any parts for the 2019 Mac Pro you could possibly want through service. They can get you any GPUs, RAM, SSDs, housing and what not. Apparently he also told me that Apple will still continue to supply and produce parts until at least 2030, so exactly 7 years after the device has been last sold.
The prices are very hefty though, two W6800X Duo modules still cost around 4k$.

Well it did make sense as to why Apple did not provide support for the 7XXX/8XXX/9XXX Radeon series, look at the Metal benchmarks. The 6950XT STILL dominates the benchmarks 5+ years after release, so if they kept supporting even newer AMD GPUs it would take ages for Apple silicon to catch up 😅
Because of that, i don't buy any Apple products. Really frustrating to see the totally closed devices with no changeable parts. I mean: easy change for the end-user.
Sooo you don't buy Apple products but you are on a forum dedicated to Apple tech? How does that work? Besides, the parts ARE replaceable, it is just a matter of money.
