Don't give up on those logs just because of the ants, Nato. They don't stay in the wood and you can cut around the damage, especially with logs that big. You may not be able to get a full slab with 2 live edges and a solid middle, but you can get slabs from each side with a live edge and a straight edge. You would need that for a table top anyway. I like the look of book matched live edges on either side of the top. If their common face is from the log's radius, the edges will match well and you'll get nice ray fleck across the face. You can fill in the middle with boards from the other side of the log that will also have quartersawn faces with similar ray fleck. Most of the red oaks I have sawn here have come down in the wind due to heart rot, but I still get a substantial yield of quartersawn boards out of them. The clearest lumber comes from near the outside of the log while ant damage tends to stay near the middle. I cut the middle out even if it's solid, since the pith looks and behaves differently while drying.
I would question your moisture reading of 22%. That's almost air dried EMC and you wouldn't get near that on freshly cut slabs.
