Wouldn't passing through GPUs automatically provide enough information to tie all your VMs together? Unless someone has found a way to make GPUs pretend to be common consumer GPUs and not report any individualized fingerprints, then I would think that any online service that has GPU access can easily fingerprint you. Plus, in my experience VMs also tend to report a lot of system information that makes it apparent what hypervisor and virtual devices you are using. Sure, each VM may be isolated in the sense that they each have their own apps and isolated file systems... but that is exactly what sandboxing does, except without the overhead of complete virtualization at each layer. I'd guess that Windows Sandbox would provide the same security in a much more efficient manner. On Linux, the integrated sandboxing solutions should also provide isolation like a VM but with better performance. I understand Qubes design decision, but honestly think it is a bit antiquated and cumbersome when in reality you don't gain much compared to other solutions.
