Nah.. HP is bigger. HP works for kids, grewup with HP young adults, Moms AND Dads. And it has a role play element and is human relatable.
Nintendo has broad appeal in youth, but you're going to find less attraction from older Moms, etc compared to HP. A 45yr old mom is going to love HP and Wii fit, not Super Metroid

Plus much of Nintendo's IP is not necessarily human relatable... so there is no role play, immersion like there is with HP.
Nintendo in a theme park is about being wow'd, cute, nostalgia and merchandise.
