You can take an example from them, but the Wiim amplifier should be different from it.
It can be a choice: integrated amplifier and mono power amplifiers. Eversolo is still an analog amplifier and there are many similar ones. There are many analog class D devices based on Hypex, Purifi etc. to choose from.
But if Wiim were completely digital, it would be above the competition. It would not need a DAC, because it would be a DAC itself. Even Mini could be a good source with a preamplifier.
I am currently looking for such a used amplifier, but it is very difficult, because people do not sell them. That says something. I've only seen one Sabaj A30a, but I don't like it.
If Wiim announces such a project, I do not buy an amplifier, I just wait for Wiim
