Friend and I

So my friend and I are planning to do an arg, but we can't think of any ideas for a two player one. We need it to be two player specifically, we have no other friends to help. I'm a bedrock player and she's a Java player, but we have a server we can do it on(hosted on Java)

Here's some info:

My friend is a pro builder, dies a lot, but has creativity with builds and ideas, sometimes procrastinates.

Meanwhile I get called a pro decorator by my friend, doesn't die as much as my friend, can do redstone somewhat, and prefers to do smaller builds.

Anyone got ideas?
