I recommend not going down the BG on a stick route. The flatness of the fingerboard can only give you bad juju at both ends forcing you to adapt your techniques to its cranky form.
The Stagg has holes for the rests both sides. You could make a set of more substantial additions to better mimic a full body experience and use those holes to key into. Kinda defeating the main aim of the stick ie portability, but suits your purpose.
