Yes. Transmogrify specifically modifies the base value of the attack, which is the value that fract replication copies, and as snatch is now an illusionist attack, fractal will copy all of its base abilities (8 
2 
and draw a card on hit) but not any gained abilities (phantasm and go again)

If the line was: Transmogrify (Red) -> Snatch (any color) -> Snapdragon Scalers to give it GA -> Sweeping Blow -> Fractal Replication
Does Fractal get GA from sweeping blow?

Yes, as sweeping blow is an illusionist attack and has go again as a base ability
