I would like to "front load" the experiment with the two very different cable geometries and construction types to maximize the chances of your hearing a difference. In the case to the two different cable geometries there is at least a measurable difference in LCR parameters and their real world performance with electrical signals to base the possibility of your hearing a difference on. In the second case of cable break in this is a phenomena which to my knowledge isn't currently measurable. The first test with two very different cables would serve to establish a threshold of detection hearing wise. If you can't detect the difference between the two cables with very different geometries then it is unlikely you will hear any difference between two identical cables regardless of their break in condition.

I'm not really that interested in comparing wires. It's boring.
It is, of course, possible to create wire that sounds different by being abnormal in L, R, or C. I don't think that is in dispute. I don't know whether the two wires you propose differ in these areas enough to be audibly different or not. I don't really care, to tell you the truth.
I stick with coax of reasonably low capacitance. I have heard what OmegaMikro unshielded wire does to a system and I don't care to inject large amounts of garbage into mine.
I'm willing to test break-in, but that's as far as I go. I consider the wire issue to be resolved, and I don't need to establish my hearing acuity. I've done enough tests with other people to show that I'm normal in that respect.
