Returning a dynamic object across a protection boundary is just as annoying as it is when caller and callee are in the same protection domain, and you can use the same methods to do it. Caller can create and grant-pass a result area for callee to fill. Callee can allocate a new object and explicitly grant it to caller. Caller and callee can share an allocation arena set up in advance and used for multiple calls. Callee can call a trusted registrar that receives and holds the object for caller to pick up later after callee returns. And so on.
