of course you might use BBD-modules for this too. But be careful: The
BBD module alone won't sound like a leslie. You need two of them, you
need two VC-Pan, and you should also use a State Variable A121 or
Steiner Parker Filter A101-1 as frequency splitter. You also need two
LFOs. Some Slewrate limiters as LFO delay for the filters would be bad
either.
