I am guessing you don’t hear more about the banana style lures is that they don’t sell well in the US. Those baits look a bit funky and ‘old-fashioned’. They typically don’t have the better paint jobs that other baits have.
I still use the Heddon Magnum Tadpolly and Clatter Tad (rattling model). They have a very strong thumping action, great for murky water. It comes through cover well because the belly hook is shielded by the curve of the lure. It backs out of most snags because the rear is bulbous and the whole back (top-side) of the lure has a smooth curve to it. The lip is part of the body which also reduces the chance of snagging. Once stopped, the bait floats up slightly away from the caster freeing itself. Unfortunately, it was discontinued.
There are some banana style baits around like the Lindy River Rocker, Rapala Tail Dancer, Reef Runner, and Flatfish.
I think the key to making one would be to weight the lure so it floats rear-end up at around a 45 degree angle. With the smooth slope of the back and weighted properly, it should back out of many snags.
