Preview InstanceReference before baking

Hi all,

is there a way to preview a imported instanceReference object in rhino before baking?
At the moment i import a instanceDefinition Geometry and his coresponding InstanceReference Xform Transformations to get a preview before i bake it.

What i need is exactly what the transformNode in Grasshopper does but i am unable to duplicate the InstanceDefiniton Geometry and apply the InstanceReference Xform to it.
Any help to do this is welcome

Grasshopper is not able to show a InstanceReference Geometry.

import Rhino as rh
import scriptcontext as sc


File = rh.FileIO.File3dm.Read(x)


# Get InstanceDefinition Geometry and Id by Name
Obj = []
ObjId = []
for i in File.AllInstanceDefinitions:
    if i.Name == y:
        ObjId.append(i.Id)
        for o in i.GetObjectIds():
            Obj.append(File.Objects.FindId(o).Geometry)


# Get all InstanceReference Xform Transfomations 
TranObj = []
for i in File.Objects:
    if i.Geometry.ObjectType == rh.DocObjects.ObjectType.InstanceReference:
        if i.Geometry.ParentIdefId in ObjId:
            TranObj.append(i.Geometry.Xform)
RTranObj = list(reversed(TranObj))


# Add InstanceDefinition to the document and get Index
sc.doc.ActiveDoc.InstanceDefinitions.Add(y,"",z,Obj)
InIndex = rh.RhinoDoc.ActiveDoc.InstanceDefinitions.Find(y).Index


# Add InstanceReferences to the document
TranObjRa = []
for t in range(0,v):
    TranObjRa.append(RTranObj[t])
    if u:
        sc.doc.ActiveDoc.Objects.AddInstanceObject(InIndex,RTranObj[t])
