I'm a bit puzzled by the question here. I would agree with Alan that sending an aircraft on a SID but without any intention of allowing it to reach the end of the procedure is a recipe for errors and misunderstandings. Presumably the SMS in use at the unit will require the possible problems to be identified and addressed. I guess this will mean that such problems will be considered.
Looking at it from a practical point of view, if you have a regular need for non-airways departures to head off in a particular direction then introduce a published procedure that does just that - with a unique name.
