Yeah I think you make more change if you write Cyclomedia Technology and ask them to create an addon for MSFS. That way they have an excellent showcase of the quality of their data and the usage of their API. If you would bring it that way they might see the added value. Otherwise implementing such high quality data is really expensive.
Height data is also pretty good available using pdok.nl (think 25cm resolution) but don’t really see a nice way to combine it with also available aireal pictures and something like Google Streetview for the sides of buildings.
Just flew a bit with a chopper over Amsterdam and it sure doesn’t have the quality as some USA sites.
