There is some help with converting B-Format to
two-channel UHJ (and vice versa) at:

http://pcfarina.eng.unipr.it/Aurora/B-Format_to_UHJ.htm
http://pcfarina.eng.unipr.it/Aurora/conversion_between_uhj_and_b.htm

Also, rather than start from scratch, you might
want to investigate convolverVST and BruteFIR.
(You may already know of these.)  I have never
used them, so cannot help further.
