I see.No.
He can't.
There is no Swordfighter.
Only Gunner.
Honestly, I think most clones are very different from their original fighter. Of non clones, the only characters that I find to be incredibly similar are Corrin and Marth due to the former's nerfs making Dragon Lunge pretty garbo. Even so, he does have enough to at least stand out what with his dragon finger Forward Smash, dragon toe Down Smash, and arm mouth projectile.
Ugh. Corrin has so much body horror when you stop to think about it.
Also, I forgot that traditional characters can have creative aspects to them. Anyway, I can't see how Corrin is so similar to Marth, but maybe it is because I have not played as Corrin as much.
How would you describe Corrin's body horror, anyway?
