Two suggestions:
1) Try some of the scented Lakeland blends, such as Ennerdale Flake, Kendal Flake, and Bosun Cut Plug. They are blended with some very potent (and tasty) aromatic agents, often floral in nature. Some smokers despise them, but some absolutely love them. Broken Flake #7 has some vanilla notes.
2) Buy some Five Brothers or some Gawith & Hogarth Kendal Kentucky. These are neutral, powerful burleys with some HEAVY nicotine. Just mix them into your aromatics untl you get the preferred balance of strength/flavor. I would start with, say, two parts aromatic to one part burley.
