Mike I don't have ceramic fiber blanket but will see if I can get some from the big box stores. I do have QT and ceramic drill bits. My lid is rather shallow so I may have to chop the corners off the QT. Right now there seems to be sufficient heat in the dome to char the cheese in 2 min. I just need to direct a bit more of the airflow to the inside of the crust/rim. I may need to move that air deflector closer to the lids edge.
Thanks for the tips. At one point I did have a round slate stone in the lid but didn't notice any difference over the aluminum disk so I went with metal to save sone weight. I'll try the QT though.
I wouldn't buy things that need a professional grade, given the temps we're working with here, from a big box store. I checked Home Depot for that particular item when I built my LBE and they had nothing that was satisfactory to me. Maybe in your area they do, I don't know.

They sell them at 1" and 2" think.
Axner sells insulation by the foot and cut it precisely to your specs. They even called me and asked how I needed it cut. At no additional cost, if I remember correctly.
It's a great company with lots and lots of supplies which could turn even the biggest BBQ into a great, custom-made pizza oven with a bit of imagination, a nod to adventure and a drive to produce a great pie. But I digress.
In order to increase air flow, and therefor be able to direct it in a better way, I'd try a heat up without the sand buffer bucket you have on the bottom, if you still use it. Dial the flame in on a medium-low (listen to the sound and characteristics of the flame...make sure there's still some yellow in there) and see how your MBE behaves.
If it's too much to handle for the MBE, put the sand buffer bucket back in but I honestly think you don't need it if you use a good temp control from the outside.
It should work, did on mine but then again,...yours is a tad smaller and might need different mods.
