I don't understand the difficulty. If the function value could be
defined in uniquify.el, why cannot a symbolic value be defined there?
If the symbolic values are specific to project, simply let-bind
uniquify-dirname-transform to the value of the appropriate project.el
defcustom when project.el calls uniquify.

That's a minor issue, just use "buffer's directory" instead.
But I wonder why uniquify does something counterintuitive like that.
