For your information -
For rapid band combinations and pan-sharpening of the latest
Landsat-8
satellite imagery, you may take a look at the free and advanced image
fusion software from GeoSage.
The software with 2 simple button clicks:

If you have the latest QGIS installed, click the 3rd button for
GeoTFF ->
KMZ conversion.
Hope this helps.
Kevin, thanks for the info.
I have tried this tool in the past and it is very nice. However, it is
not open-source(d). That's a huge blocker in trying to understand what's
being done with the data exactly. It would be awesome to have access to
the source code and try to replicate it for grass (credits to original
authors are always respected, of course).
If you work with grass under Linux, you may want to try out the
replication of the HPFA Image Fusion Technique for grass (a bash shell):
<https://github.com/NikosAlexandris/i.fusion.hpf.sh>. I my opinion, it
outperforms the rest of the available techniques, in both image
sharpness and preservation of the original radiometric properties.
I have a work-in-progress python version of this script which I am
trying to finalise these days (and hope it will meet the criteria to be
included as a grass-addon at some point).
Nikos
