You can extract subdatasets one by one and combine them afterwards using
gdal_merge.py tool and its option '-separate'. With this option input
images will be threated as separate channels of the same scene.

Also you can save one step and do not extract images before merging,
just use subdataset names as input parameters for gdal_merge.py.
