How to open some files based on extension rather than mime type?

[Israel]

You could of course use:

/usr/share/applications/defaults.list
This hold a bunch of the values you'd normally set using xdg-mime
It usually contains stuff like:

application/rtf=libreoffice-writer.desktop

application/tab-separated-values=libreoffice-calc.desktop

application/vnd.lotus-1-2-3=libreoffice-calc.desktop

application/vnd.ms-excel=libreoffice-calc.desktop

application/vnd.ms-word=libreoffice-writer.desktop


Which you can change to whatever you like.
This should effect using things like:
xdg-open mydoc.rtf
from the terminal, and probably from any application that looks at xdg
mime types.
The first line in my above excerpt defines that
libreoffice-writer.desktop will handle this.
