It could be funny to just have him drop a seismic charge in it as he’s flying by. That seems like the whole reason they came up with the scene and they just came up with a convoluted reason for it to happen.
When he was slowly creeping to the Sarlacc, I thought he was going to just start unloading on it à la Kylo at the end of TLJ. His face emotionless as he fires into the pit a comically long period of time. He stops and Fennec asks “You okay?”. Boba replies “Just business.” and flies away.
