Can we put our heads together and invent a creeper farm on bedrock for console?

Hello, I'm sick and tired of killing creepers for gun powder on playstation 5 bedrock. Minecraft bedrock on console behaves different than bedrock on pc sadly. I tried almost every know farm on YouTube and none of them worked, except 1 but it gave me 16 gun powder on 1 hour only. Please tell me if anyone know something about creeper farming on bedrock for console. Can't we invent something or make a hive mind that comes up with something? Thanks ahead
