No, this is not TWODABS. 
 ::* TWODABS applies when you have a primary topic and a secondary topic, and nothing else. You are proposing to have one become primary. You can't use TWODABS as an argument to do something when TOWABS doesn't apply unless you succeed 
 ::* Further, even if you do succeed, you wouldn't be able to apply TWODABS. The DAB already exists, at , so it can't go away. You're stuck with a DAB. It is possible to delete it, but WP is very wary of deletes of redirects, because of external incoming links. 
 ::* Finally, there is a third entry on the DAB, and has been for almost 6 years 
 :: So TWODABS doesn't help you here for many reasons.
