There are actualy very vew drivers that actually support the AddBand() method (that is adding a new band to an existing dataset). And GTiff doesn't support it. In the GeoTIFF case, you can actually specify the block size at Create() or CreateCopy() time with TILED=YES/NO and BLOCKXSIZE/BLOCKYSIZE creation options.
