An interesting question. I also enjoy BF, and your post sent me wandering around various vendors, looking for bulk sales. 4Noggins doesn't carry it bulk, P&C is out, and SP has it in stock. Prices have gone up on SG blends from a lot of vendors - supply and demand - and it looks like BF is the latest SG blend to be discovered.
As to an equivalent - well, it's about 30% lat, with the rest Virginias, according to the description - no orientals. There's a lot of lat forward blends out there. Have you explored the Altadis bulk line? These are not great tobaccos, but they are enjoyable additions to the rotation, IMO. Maybe their Heavy English, 503.
Thought in the early morning, solace in time of woes,
Peace in the hush of the twilight, balm ere my eyelids close
