Assuming the blockers are 1.5 on each side, you are going to need an adjusted bottom row. Everything above that row can be the same as standard 60% though. bottom row for sure would work as 1.5,1,7,1,1.5. There might be another combo but you would need pcb in hand. The above listed bottom row would be the easiest to find keycaps for (beyond a standard 60% ansi).
