VDP2 bitmap modes, both at 16-colors

According to the docs, it seems like it's not possible to have the bitmap mode for any of the backgrounds to have 128 selectable palettes (palette number).

The BMPNA register is where the palette number is set, only has 3 bits are available for either 16 or 256 colors. For 2,048 and RGB, neither need it. In the VDP2 manual, the lower 4 of the 7 bits of the palette number are zeroed.

This implies to me that it isn't possible to have two backgrounds, both at 16-colors and with 128 selectable palettes. What about the CRAOFA/B register?
