 Could you specify any characteristics which support an origin from Lombok (or Sumbawa), please?
I can see your point but am not fully convinced yet...  
  
  
 
I have seen blades with a somewhat similar profile from the Riau archipelago; the greneng may better fit with the suggested eastern origin though.
Same-o with the selut which Detlef attributed to Sumbawa which IMVHO doesn't look close enough to the examples mentioned to ascertain this origin...
