Yes, there's such a way, more over, it will be just a small subset of a richer language that is widely used already, so it will require very little coding. When there's a need in SPARQL-like extensions, like subjects-as-literals, there's a straightforward way of serializing data as SPARQL fragments. Note that in this way not only subjects-as-literals are available, but even SPARQL 1.1 features like path expressions or "for each X" expressed as "?X" in an appropriate place of an appropriate BGP.
