Is it possible to wrap an existing function with another function using the same name in fish?

I'd like to create a cd function which expands on the current cd function which (on my machine) lives at /usr/local/Cellar/fish/2.6.0/share/fish/functions/cd.fish. Is this possible?

So something like this:

function cd
    if i_can_handle_it
        do_my_thing_with $argv
    else
        call /usr/local/Cellar/fish/2.6.0/share/fish/functions/cd.fish $argv
    end
end

You can't have two functions with the same name. You can have a builtin, function, and external command with the same name. The standard solution to this problem is to first rename the function you want to wrap: functions -c cd cd2. Then define your cd function that calls cd2. Note that this works regardless of whether cd has already been run and thus defined because changing the name first causes it to be autoloaded.
