No, you cannot dictate the canon policy. The creators of the unvierses involved dictate it.
Also, BDZ cannot be dismissed because it has occurred multiple times in the SW timeline.
More evidence of SW's power comes when a single transport fleet took away a planet's entire oceans and the Empire enlisted one private shipping company, Black Sun, to carry out raw-material gathering for and supervise construction of DSII and the Empire had almost completed the project in a matter of month, despite the fact that one company was transporting all the materials and the project was totally secret until the plans were conveniently "leaked" to Bothan spies under Palpatine's orders so as to lure the Rebels into a trap. Were it not for the mother of fluke victories, the Empire would have won.
Even without BDZ calcs, the Empire would win because of (a) the MT-level calcs derived from the TESB asteroid scene, (b) the obscene number of ships the Empire has (25,000+ Star Destroyers and possibly millions of smaller ships), the superweapons the Empire has (Death Stars, Eclipse, Sovereign, Galaxy Gun, World Devastators), and several B5 scenes, including the 2MT nuke scene, the Excalibur-vs.-asteroid scene, and others.
