Thats the point ( question ): bothered or no bothered of how it looks when mounted. Also need to find out your country regulations on front view obstructing devices, in many countries it is a strict.
Besides V40 mirror bracket hoursing is more user-friendly I would call from point of view dashcamera mount, because it has extra space from one side ( right side if look from outside ) where you can mount dashcamera the way it will blend in with rearview mirror
XC60 mirror bracket housing covers entire mirror length
I would try Mobius as mentioned earlier and if you like it, - you leave it front, if not - then can use it as rear dashcam like

I did quick photoshoping
Because mirror mount housing is close to horozontal line ( flat to surface ), it is easy to attach mobius with dual lock 3M "velcro", or do some DIY using neodymium magnets.
Maybe you find some ideas from my projects

But of course it's up to you to think:
- how discrete you want dashcamera look,
- what is crime rate in your area or place you live or where you plan to drive,
- do you afraid ( risk ) leaving bulky ( visible to outside ) dashcamera overnight ( - day ? ) inside car when parked not at home garage,
- do you want to remove your dashcam every time or only for overnight,
- does local legislation allow additional gadgets on windscreen
etc.
