That makes sense. I'm merely pointing out that, since the purple in BP looks like that because of the pattern as opposed to the pigment (it's probably the technically the exact same shade of aubergine as any other purple bean, it just that being in little itty bitty speckles spread out makes it a lot lighter) trying to get it to transfer may not work. You may get a JC pattern bean with lavender replacing the maroon. There certainly are beans that are very much like that, like New Mexico Cave (basically JC with brown instead of maroon) or any or the orcas or calypso's (once you set aside the different bean shape, their actual seed coat patterns are certainly similar). But it seems to me that what you are more likely to get is a JC maroon on white pattern with the BP purple wash OVER it. Pretty certainly, but not exactly what it sounds like you are looking for.
