it is definitely possible, but the question is at what effort?
NDI Tools have a section on their website for developers, so I guess it should be possible to create an integration that can display NDI streams. Feels like it would not be a simple job though
As Paul says, it would be a lot simpler and already possible with various free modules, to just composite in the TD visuals, or Chroma key them in OBS
if that is too involved, you could try using the LowFatMilk module, its pretty cool
