You should be able to see the dimples on the inside where it is spot welded to the inner roof skin. I think you should be able to drill out those spot welds and keep this interior piece intact. Your new panel will need to be spot welded back to that inner brace. Your replacement panel is sandwiched between the inner a-pillar and this interior brace. Will be tough to get it in but doable i think.
I was thinking the same thing.
And yes, you can easily find the spot welds around the sun-visor mounting holes. The very first photo I linked to shows where I marked some of them with a black marking pen.

It is important to use a spot weld drill bit and use it properly. It's way better to avoid drilling through the brace behind.
I'm sure the one from HARBOR FREIGHT isn't the quality of others out there but for $4.99 it's not bad.
I'd say with care it will last for drilling out 25 to 50 spot welds.
