Si4732 + BK1080 on same communication lines? Is this real or a joke?

[u666sa]

You are looking at photo of Quansheng UV-k5 board with Si4732 dauther board modification of unknown (yet unknown) version. On top, you have the stock BK1080 fm chip. Question is this. Could this be a joke photo someone made for funs? Or, perhaps this is a possibility? Two chips at the same time?
Usually we remove Bk1080 and install daugher board in its place.
..
There is only one firmware that lets you select between different radio, r3b0rn by fagci, but it's either one or the other. Mod where you keep two chips is unknown. Something tells me this is a joke.

Not considering the RF side, the communications line is just I2C.
As long as the BK1080 and Si4732 don't have the same address, it should be fine.
