No, that's not how planeswalkers work.
Fighting a Planeswalker
Planeswalkers can be attacked. When you declare attacking creatures, you choose whether each one is attacking your opponent or a planeswalker that opponent controls. Your opponent can block as normal, regardless of what each creature is attacking. If a creature deals combat damage to a planeswalker, that many loyalty counters are removed from it.
Other sources can deal damage to planeswalkers. If a spell or ability you control would deal damage to an opponent, you may have it deal that damage to a planeswalker that opponent controls instead.
So since you control both the Planeswalker and the damage source, you can't redirect it to the Planeswalker.
