Stepping stone walkway + boxed hedges on the side?

 I've latelly been thinking about how much I love the look of grass in between paving blocks/rocks or whatever they are... I mentioned this to MrB once before and he didn't like the idea. Should I try again? Would this look nicer than an exposed aggregate path to match our driveway?

Would this work with the boxed hedges that I have planned for either side of the walkway? Probably not, hey? Because I don't want grass under the boxed hedges... Hmmmm :(
