Good that your drilling went well, my spinners seem to spin pretty readily.
I might work out my own anchor system if I decide not to take the headliner out. For now, I got 2 spinners in the back but I'm not done yet there. I'm going to go easy in the front and Kroil them well, in the hope that those at least come off then I don't have to deal with the sunroof hopefully.
RT, you still pretty sure that if I overKroil the Front it'll just go in the pan, not the headliner, right?

My spinners were still tight enough to drill wile the rack was attached, give it a try, that Phillips head is useless to you on the spinners, you have nothing lose, #11 or 3/16 bit will do nicely, lube and light pressure should allow it to be drilled just fine
You do not have spinners in the front yet? This is good
Doing all you can on the front to prevent sunroof pan removal, I would go strait to drilling the heads off so you can get directly to the screw/nutsert joint and apply kroil directly to where it needs to be, also when you attack the screw to nutsert joint you can watch and see what is going on, where as with the rack feet in place you are left wondering, “is it spinning out or is it spinning the nutsert?”
Yes any oil that drips through the front row will fall into a fiberglass pan, from this posts and others I do not think you have a grasp of the sunroof pan (neither did I) look at the height change of the headliner, this is where the pan ends.
I drill out a lot of fasteners at work, maybe several thousand a month? , one that always spins are small pop rivets used for nutplates (3/32”) after you establish a center so the drill will stay you can bring the bit over to about 20* and even though the rivet and bit are both spinning at the same speed the cutting edge of the bit moves foreword and backward on the surface because of the angle, if yours spin try that out, it will take a wile on this relatively large fastener (3/16”) but it will work even if it spins

and another idea, maybe more reasonable:
I drill or grind the spinner screw heads off (if they don't spin too much).
I remove the rack.
I'm left with a screw in a spinner.
I put some Kroil on the screw.
I clean the nutserts off with solvent (how?)
I put some penetrating superglue under the nutsert flange to glue it to the roof metal.
Then I remove the screw if it will come off.
Then I'm golden if the rust is not too bad...
waddaya think this time, eh
?

You can always try it, but the root problem here is that the screw rusts to the nutsert, that is a lot of surface area, it is not that the nutserts are not installed incorrectly just that the screw/nutsert interface is a lot more rotational strength than the nutsert/sheetmeatl joint,
At work we call these rivnuts they are junk, we use them to hold up small signs and other light weight cabin crap that is not worth getting to the back side of, that is why they use them here they used them here they hold long enough to install the rack
I do not think that glue will reinforce this joint sufficiently enough the do what you are looking for, if the screw is really stuck it will just brake the glue, the sheet metal is so thin and the flange so small there is just not squat for strength available here
Here is my recommendation:
You already have spinners in the rear, remove the headliner (you are already half way there) grab on to the back of the nutserts with visegrips and take apart the aft row, drill the entire front row to get the rack off, directly soak them in Kroil overnight, and then in the morning try to remove the screws from the nutserts if the spin remove the sunroof pan and put regular nuts on the spinners or all as you desire
A possible blind option is to grind and knock the nutsets through and fill with fiberglass or some other good body filler (never bondo) and prime and paint, this was my original plan but it did not work because of circumstances
