Next time just glue a piece of aluminium on the inside of the old sump with JB Weld or a similar type of heat-resistant epoxy. Been there done that after my wife holed a few too many sumps by driving her Skoda over overly high obstacles. The first time she did this I could follow her track in the tractor to where she parked the car for me to tow it homes, the other times were out in the bush - she's a veterinarian which takes her to places where roads are afterthoughts. I just swapped between sumps, repairing the freshly broken one in wait for another turn. That car has been sold and she has not yet managed to hole the current one but I know from experience this works just fine.
