r.composite will do this, but you will get either better results or
better performance if you keep them as separate bands.

The default of levels=32 will reduce the colour depth to 15 bpp, while
using levels=256 will result in a significant increase in CPU
consumption for anything which converts cell values to colours (e.g. 
d.rast).
