David,

The most straight forward approach is to translate to GeoTIFF and then
set this new geotransform. The CEOS format does not support setting
the geotransform. 

Alternatively you could create a VRT file cloned from the CEOS file, 
set the geotransform on that, and then write to geotiff.  

Did you need to know how to copy the CEOS file to GeoTIFF?  

Best regards,
