Watcher - Creating a Payload

Hello,
Is there a way to create a new payload in the condition portion of watcher?

I have this watcher that evaluates buckets, it checks to see if the buckets pass a condition. The issue I want to filter out the buckets in the conditon and currently its passing all the buckets as the condition evaluates true which is not what I want.

  "condition": {
    "script": {
      "source": """
      def result = false;
      def filteredBuckets = [];
      for (bucket in ctx.payload.aggregations.by_host_and_object.buckets) {
         def mostRecentEvent = bucket.most_recent_event.hits.hits[0]._source.event.outcome;
         def failuresCount = bucket.failures.doc_count;
         if (mostRecentEvent == 'failure' && failuresCount > 1) {
              filteredBuckets.add(bucket);
              return true;
         } 
      }, 
ctx.payload.filtered_buckets = filteredBuckets;
return false;
      """,
      "lang": "painless"
    }
  }

As you can see I attempted to assign the filteredBuckets to ctx.payload.filtered_buckets.

I might be approaching this wrong
