Siglent SDS2000X HD Teardown - Hackable Arbituary Waveform Generator?

[LooseJunkHater]

Anyone else notice how in the recent EEVBlog teardown of the Siglent SDS2000X HD, it looks like the separate PCB is solely controlled via a USB 2.0 (5 wires) protocol or similar? It makes me wonder whether there would be a source that would pop up to purchase the arbitrary waveform generator PCB, and then be able to hack the board so that the whole scope isn't needed to use that nice 25mhz waveform generator? What's the likelihood of this happening?
