Photoshop Save As DNG please

Using Photoshop (with Lightroom) to focus stack images and for Save As, DNG is not an option. Seems strange since Adobe would like the world to switch to DNG (not happening but that's another story). 
So after stacking 5 Fuji 57 MB raw images, the result is a 1.36 GB TIF. Exporting it in Lightroom at full quality to a DNG, 102 MB. Come on Adobe, we shouldn't have to go through this extra step to get a DNG file and save over 90% of the space.

I do not think this suggestion makes sense to me.  To do focus stacking the image is demosaiced before the stacking.  The result should be some RGB format and not Bayer array format like DNG or proprietary raw formats.

Not sure what you are saying. Photoshop creates a TIF, that is the default. Converts to a DNG just fine.

If you make a stacking of photographs alone result count, therefore they were flattened picture and here is!

It does not make any sense to convert the focus stack to DNG, because the result would still be a 'TIFF in a DNG envelope'. It won't become a 'raw DNG' like the panorama DNG and HDR DNG that you can merge in Camera Raw of Lightroom. Basically it would be the same file with just another extension. You wouldn't have any of the advantages of a 'real' (raw) DNG file, but you would lose the layers that you do have in the TIFF file.
