You will end up needing to provisiom lambda size to the worst case of any one function. You need to split them if you want to use resources efficiently according to what the functions do.

Agreed, this is the biggest issue with lambda for me - particularly Lambda Edge instances.

But I find it's the dependencies and common code that takes most of the space which often is common with all functions.
