Debating Panasonic GX8 Purchase

I have an Fz1000 and like it, but have some issues. Placement of the tripod plate over the battery cover, less clear action photos (birds flying), can't go below f8, are among some of my issues. Just unsure about another camera. But have big trip to Africa coming up and I want good photos. Forgetting price, would you go with a gx8 or stick with what I have? Debating Panasonic GX8 Purchase
