Considering the birds cost hundreds of millions of dollars and on the other hand, there are proximity sensors in DIY electronics kits that cost $20. So I know an aviation-grade sensor will be much more expensive, but all around, I think they won't add more than $1000 to the cost of an airliner. So why not?
BTW, since video cameras are small enough to fit on phones now, I think there should also be a video feed from all the tips (mentioned above) to the cockpit. For crying out loud, even cars have backup cameras now. I would even make sure that every control surface is visible from a video camera that feeds the cockpit. This would prevent the recent incident where the pilot would bank left and the plane would bank right because the controls had been reversed, because when moving your control surfaces prior to takeoff, you can actually LOOK at them while actuating them, one by one.
Or maybe some or all of this has been done already and I don't know because I'm not a pilot???
For the proximity sensor part, there would still be cases where a turn has the obstacle appear too suddenly to stop anyway. A cheaper and lighter solution would be to follow the yellow lines painted on the ground.
The camera to see critical surfaces is a good idea and easily implementable on new designs. A retrofit needs power and data wiring as well as a way to get it on the cockpit screens. That's probably the difficult part as the displays on older designs weren't designed to have a video feed input from cameras.
Even a "new" design like the 787 started to be designed 15+ years ago. Cameras had just begun to appear in cell phones a couple of years earlier and not nearly at a useful resolution to evaluate ice on a wing or something like that.
Also, depending on the sun angle it will render some views useless at times unless you have a retractable tinted lens.
