I have not tried myself, but this could be a possible way:

#import bil files
r.in.bin
#create strds and register maps (per variable)
t.create
t.register
#convert each strds to 3d raster
t.rast.to.rast3
#export to netcdf
r.out.gdal

For time series issues, there's this wiki:

therein

Now, I'm curious if it will work ;)

Cheers,
Vero
