I know this sounds stupid as forget, but please hear me out.
It would be cool if we had a boomerang with a grenade comically tied to it, that if standing still, it flies off for about 50 studs, then returns back to explode at the point at which it was thrown—if standing still. This would work well for setting up "traps," much like cooking a grenade, except you could get out of the way first.
The next application would be to use the inheritvelocity thing to make it so you can arc it around corners and hit guys hiding on the other side.
Also if it collides with players or vehicles, it should just explode, but if it hits a brick or the ground of the map, it should stick and explode in the amount of time it has left, so you could stick it in walls, either within view or around a corner to set up a trap.
