A buddy and I just managed to conquer them sites in highsec on SiSi and I hope it will help you along.
All you need are one or two Golems with explosive cruise missiles.
The thanatos does have 62.15% explosive resistance and since I only had explosive with me, it took a while to get the armor layer down. My estimate is that it is above one million ehp.
However the minmatar carrier has 0% explosive resistance at all layers, so you will have an easy time, shooting the shields down, after which the armor and hull ehp go down fast.
In both cases shoot everything you can until the carrier lands and stop shooting anything but the carrier.
I was flying a Raven Navy Issue which I made cap stable and 8x torpedo launchers.
I am guessing a Golem can solo those sites with t2 cruise missiles, precision for the frigates and cruisers and fury for the carrier(s).
Or you have 2-3 (4 or 5 with low skill points) Ospreys and 2x Raven. The logi will get webbed and painted, so be careful.
