Don't you think Ranbir Kappor and Katrina Kaif would make a very cute and successful pair ?

I recently saw Ajab Prem ki Gazab Kahani - It was nice to see 28 yrs old sweet hero and 23 yrs old charming heroine. I think it is going to be terrible to accept Amir Khan , Salman Khan , Shah Rukh Khan and Akshay Kumar as romantic heros when all of them are touching age of 45. No one would comment on their acting talents , they are great. But to see them dancing with herione half their age looks odd. What is view of others ?
