I typically use modules and adventure paths as my adventure bases but run games with those modules in a fairly sandbox way in my homebrew mashup setting.
I think worldbuilding a kitchen sink type setting is fairly useful for those types of purposes. Golarion or Greyhawk or Forgotten Realms or Midgard types of setups where there is a lot of different flavors and options of places. So it is then easy to place and run a gothic horror mad scientist adventure or an Arabian nights adventure or a hunt down the apocalypse cult one.
In my mashup setting I have a bunch of individual setting pieces I like a lot with specific flavors (individual Golarion nations, Ptolus Empire, Freeport, others) and it is easy for me to throw in different modules that I am interested in running. I have run Freeport City/Pirate/Cthulhu investigation campaigns, a deepest Nyambe fantasy African one shot, a Reign of Winter Baba Yaga/Narnia White Witch/Fey campaign, a Gothic Horror campaign, and an Iron Gods sci-fi-fantasy mashup campaign, and more all in the same world backdrop with connections making sense for me.
