I am using FME2014 and I have two custom transformers that are used in my workspace. The first customer transformer that is used has inside it a VariableSetter which I set to a Global Variable.
In the second custom transformer I use VariableRetriever to retrieve the Global Variable. But it doesn't seem to work.
Are you able to retrieve variables in CustomTransfomers? Note: I have set both custom transformers's Attribute References Setting to: Advanced - Fix Manually

I do have Setter/retriever combo's.
And yes you can do what you are doing.
..feel the but comming up yet?...
You're proces must be set up in such a way that when the Retriever is called, wherever it si, the called variable must be set already..:
SettIt is a variablesetter in a custom and ReadPara a vriablereader. Nothing else
In pic1 ReadPara2 succesfully retrieves the variable, but ReadPara does not.
In pic2 however both manage to retrieve it!
Reason is, i inserted a couple of processes slowing down the bottom stream.
so, yes u can or at least it is possible.

Because the feature holder in the pick is not in the same stream, or does not use required elements used the SettIt.
I think if the holder holds elements required in SettIt, it might be enough. (though i didn't test this).
On the other...wait!.
Ok, this works too. Create a "Waiter".
The waiter Retrieves the variable you set (or are trying to set)
And then tests it. Until it ha "arrives" the Waiter loops.
I use Missing and Empty and not Null.
(but you adaept test to suit your requirements of course)
This works neatly :)
