Unfortunately I don't think the case you highlight here is not possible to fix (RType.of(classOf[BigObject.LittleThing]))
Here's the problem. When you use the compile-time square brackets, much more information is available. You get:

TypeRef(TermRef(ThisType(TypeRef(NoPrefix,module class scala_reflection)),object BigObject),class LittleThing)

From here you know that you have a BigObject$LittleThing.

When you use the runtime parentheses for 'of', you get:

TypeRef(TermRef(NoPrefix,val <none>),LittleThing)

This tells you nothing except that you have a LittleThing. It erased the rest, unfortunately.
