I have mocked up a crude sun blocker it did work of a sort to try and stop the ingress of misty water over the interior, however fitting a traditional proper roll over bar without serious modifications is impossible unless your about 5ft tall and have the seat forward. And whilst the librands bar and fittings are a piece of engineering it might tighten up the chasis a bit on a trad but as a roll bar for most people its as much use as a chocolate tea pot.Roll hoops with fittings through the floor might be dooable but could end up being more cosmetic than an actual safety item.
