Bare in mind the BL602 is a very new device. In theory though, even if the DMA buffers cannot be remapped, we can enable any chip we like. I can't see how such a thing can be prevented.
Basically, it should be up to enabling the right CS (chip select) line, which should equal to using the right SPI lane. However, it all depends on the way quad-SPI IP core is designed, which we simply don't know. One of my concerns is that no additional documentation about the BL602 will be available, but the publicly availlable source code should provide the means to fill the gap.

How do we contact Pine64? All my recent attemps have failed, which included email messages, forum private messages, and pings in forum posts. They have even remained silent to a thread like this, which is very concerning; why should they ignore an opportunity to improve one of their flagship products?
Also, please keep in mind that I might be able to produce a small batch of devices, once the pandemic is over, but that would need to be a device that people would actually want to buy. It is good that the BL602 IC is available for purchase separately in the Pine Store, which makes it possible to include it into the BOM.

I agree, there are many uses for such a device.
