Awesome! Thanks Jukka, that has fixed it. I didn't know wkbUnknown could also
be used as a wildcard, but with that tag I don't need to set geometry fields,
GDAL manages to find everything and make it appear as if everything is in one
layer.

Hi,
Partial answer based on editing the example

Sources: polygon shapefile and point shapefile
Output: one layer with unknown/any geometry type
