I may misunderstood, but do you suggesting that i should reduce the bitdepth to 12-bit before quantization?

Straight approach. I quantize the palette to 5-bit (2-32 colours), then i create the imaginary second palette over the index of 32 and then i just use the extended table in the eucledian colour search with the imaginary colors too.
