It's possible, I mean it's already happening (577k vs 247k) but i think the PS3 will sell on average no more than 50% extra on the Wii U. It's quite hard to see what Wii U will sell like in 3 to 6 months time, as i don't see PS3 really affecting it either
Xbox One, PS4 and Switch (+ Many Retro Consoles)

Prediction: Switch will sell better than Wii U Lifetime Sales by Jan 1st 2018
