Are you always 100% satisfied with the view that is given by searching the site location?
If not than the time savings of launching the snipping tool, saving the result and inserting into Revit isn’t going to be as significant as you’d hope. My guess is that process takes 5 minutes to perform in total, per project. My gut says that the time to build the customization in Dynamo to export the google map view is about 4-6 hours if you were building it from scratch, more or less depending on your level of experience. Maintaining it will be about 2 hours per Revit release or Google API change (not sure how constant that is but I would wager it’s very stable), so you’re looking at about 84 (7*60/5) projects to break even in the first 12 months (assuming equal billing rates).
That said if you’re feeling ambitious or if the ‘first view’ is always correct you could look into Dynaweb and the google maps API to hack something together with no UI around the view.
