Check what tools psychology has for quantifying subjective assessments - they exist. One common test for example to assess depression level state uses a set of questions and scores accordingly. There are other questions that have "on a scale of 1 to 10" - and of course you have to adjust for other factors. It's not trivial effort to do this right but not impossible- to at least get something useful.

Yes, you could make a good test based upon some questionnaire. I am not so good at that discipline - but it could be 20 questions regarding the image quality. Like

Do you find the far away details look sharp?
Do you find the far away details look clear?
Do you find the far away details look natural?
...

Then you get a mix of similar images taken with different cameras, where some are taken with both a Foveon and a non Foveon, but ... sometimes both are from the same kind of camera.

But ... probably you need a certain population and a certain amount of images. This test is not cheap.

Moreover ... it is not clear who to choose. Random people will not see anything interesting. It needs some amount of skills to even understand the questions.

None of what you said is unsurmountable.  The test being cheap or not is beyond this argument.  This can be done, but it can not be done carelessly.
