I believe you can also output to BMP8 eg: BMP8:outputfile.bmp

There's no BMP8 format:

$ convert -list format | grep -i bmp
BMP* rw- Microsoft Windows bitmap image
BMP2* -w- Microsoft Windows bitmap image v2
BMP3* -w- Microsoft Windows bitmap image v3
WBMP* rw- Wireless Bitmap (level 0) image

Try adding -compress none to your command line to produce uncompressed BMP images.
