I tried to answer this question but I'm even confusing myself.
However, even though I routinely attain these 'clairvoyant states', to call them something, I can safely say I'm the example of the person who is not naturally clairvoyant, so I can tell you all the things that came to mind when I read your post (darn, that was confusing anyway).
I have a tough time maintaining a visual construct in any shape or form. So far it's been my biggest weakness in the exercises I've been doing. So for someone like me, the act of maintaining a visualization can be more challenging that establishing it. So the act of achieving the visualization in a way to be able to maintain it (so that your construct is really what you're linking to and not whatever seems close enough) would be a superhuman achievement for me. Then to be able to link it to something like the ether (or AR) to the specific info I'm looking for is another thing that would be enormously difficult for me.
I never tried anything of the sort, because I'm naturally empathic, so I usually know when someone's lying to me (or likes me, or hates me, etc.). So I guess that what I'm getting to is that it depends on where your abilities lie.
If you're not naturally prone to clairvoyance (as I) this effort would be incredibly complex engineering, but if you are good at visualizing and not naturally clairsentient (which is close to what I am, as I suspect most of us) then maybe this approach would be probably helpful. Especially if you're the cerebral type.
The 'hunch' is all I need. So far it hasn't failed me.
I know, that wasn't very helpful.
