I was humming and hawing over it and thought of a possible solution but I am not sure if it will work. This was kind of inspired by my tie down points.
I was thinking of using the existing tie down point or grabbing some thin steel of metal with holes drilled and tapped into the T then adding a long high grade steel bolt into the piece with washers and rubber to cushion it and increase the height as well. Should not cost me more than $20 overall for the parts and would add 6-8 mounting points (3-4 on both sides).
It's hard for me to explain so I will show it through a picture.

So basically: Bolt -> metal washer -> roof rack -> metal washer -> rubber -> mount point in T
My concern is, would that even work? I know I would have to elevate it a little more due to the curve on the roof but what about weight both in load capacity and weight distribution? I tried to find out the load capacity of the factory tracks in the FSM but nothing.
If you think this is a bad idea, tell me so and I won't be upset. Just thinking of a possibility. I still have one of the factory cross bar, I would just have to find another one... just not a lot of luck in that department.
