I had lacebite issues for years, as I have high arches/high volume between my heel and top of foot where ankle meets.
The True TF retail skates have been the best for me that I have tried, including Graf, CCM, Bauer. They are sized a bit bigger to begin with (rule of thumb for most people has been dropping a 1/2 size from CCM/Bauer) and are incredibly moldable, which should help accommodate the added volume it sounds like you have.
On a side note - I've found Graf to be only slightly shorter than a CCM/Bauer boot. I had almost identical fit in a Graf 5 and CCM 4.5. Going 1 full size up from your current Bauers into Grafs is likely too much.
