Yes, I have “oversize” wipers, it’s a great idea. I can’t remember what size I ended up with – the only downside is that the offside misses the last bit of glass at the bottom, where it curves round.
I’ve also moved mine round on the spindle to get maximum glass-wipe where I look – mine is LHD. They were too far down and therefore stopped well before vertical.
I can HIGHLY RECOMMEND Rain X windscreen water repellent (or similar products). Makes looking out of the unwiped areas of our huge screens so much better.
