Nah. RPGs aren't as powerful as you'd think. You'd probably take a couple chunks out, but if these are carved from the living rock as a single slab, polished and smoothed, glancing blows aren't going to do much.
For something like this, det-cord, ANFO, TNT/RDX, Nitro glycerin or C4 would be best. ANFO would be easiest and cheapest, as well as simple to transport in a rental van.
