I completely agree with you about the poor formatting of addresses in SPW API. I believe SPW geocoding API is not using PICC or ICAR databases (even though I don't have real proof).
That being said I don't think integrating a second query in this provider is a valid solution. The Geocoder PHP providers are meant to be a layer built on top of a single API.
I really like your idea to use PICC ArcGIS Rest API to get "more" information but I would build that on top of this provider and not "inside" it.
Unfortunately, the results from http://geoservices.wallonie.be/geolocalisation/doc/ws/index.xhtml (SPW geolocation API) are returned in ALL CAPS.
This leads to inconsistency with results from Flanders and Brussels, and the other geocoder-php providers. I'll ask geoservices.wallonie.be if they can remove these caps... fingers crossed, but i guess it could take a long time.
I've also been looking for a workaround... and would be happy to work on a PR if you agree with the solution. It would imply to make a second query, with the ArcGIS REST API of the PICC_VDIFF/Address layer.
Example
1) Existing query gives 83 CHAUSSÉE DE CHARLEROI, 6061 MONTIGNIES-SUR-SAMBRE 2) Second Query: https://geoservices.wallonie.be/arcgis/rest/services/TOPOGRAPHIE/PICC_VDIFF/MapServer/1/query?where=CODEPOSTAL%3D%276061%27+AND+UPPER(RUE_NOM)%3D%27CHAUSS%C3%89E+DE+CHARLEROI%27+AND+NUMERO%3D%2783%27&outFields=*&returnGeometry=true&outSR=&returnIdsOnly=false&returnCountOnly=false&f=geojson gives "Chaussée de Charleroi", "Montignies-sur-Sambre" and both lat/lon in WGS84 and Lambert72
