I had an awesome idea for a “Robin” swap.
I think Tim is Barbara swapping roles would be so fun. The two are both  excellent hackers and support for that rest of the bats in different ways.
Tim Drake receiving an invitation to a costume party and going as “Batboy” (or even “Red Robin” or whatever you want to call him). Then him becoming tangled up in the mess and stepping in to help Batman and Robin. With Batboy eventually becoming as much of an Icon as Batman and Robin in Gotham.
A young Babs stalking Batman and Robin after she over heard a meeting between them and her father?? Give it to me NOW please!
Tim working with Dick for a while and helping Jason settle into the role. Then Jason dies and the Joker attacks the Drake family. Kill Janet, Kidnapping Jake and finally paralyzing Tim.
Little Preteen Babs stepping up into the Role of Robin after Jason’s death and Tim accident. She is spunky and more than ready to take up the challenge. Unlike Tim she isn’t there to play the perfect soldier.
I don’t necessarily want to Kill Jim off but a coma scare would certainly do the trick.
Tim coping with the sudden loss of function in such a important limbs and trying to get back into the game and struggling. Only to realize he can do a lot even if he’s not out in the field. There are things no one else but him CAN do. Taking on the role of an aggressive hacker, digital security, support and digging through different things online to gather clues from the internet. Dawning a new name he once again became a a crucial part of Batman’s team. (I also personally believe he would make his presence known unlike oracle, who isn’t a Public hero and isn’t wildly know about Tim would make it known someone’s always watching) 
When Jason comes back as Red Hood it’s not Tim he’s fighting against. He will come face to face with Babs.
Oml speaking of. DAMAIN TRYING TO FIGHT BABS WHEN HE FIRST SHOWS UP!?!?
