It probably can be adapted, but I am just someone who comes up with an idea and then try myself first, and usually need help (a lot!) to make it happen what I want 
- and I second your idea, would love the weeknumbers to be included and linked to the weekly notes. Perhaps even the months and the year, too, to their respective counterparts.
Back in the early days of Obsidian people have made a script like that, they got very far but it was abandoned. I haven’t checked it yet, it might just need a couple of edits for it to work in the present version of Obsidian. The discussion about it, with examples of the script, is here: Calendar and tasks for daily notes - #41 by afv
One that is a bit more recent and might, if further developed, eventually replace everything I have come up with myself. Looks very promising! You can find it here: GitHub - Quorafind/Obsidian-Big-Calendar: Big Calendar in Obsidian, for manage your events in a day/week/month and see agenda too!
@ninjineer and @ScholarInTraining - this is FYI too in case you want to take a look, collaborate, or anything
