I'll start with some that I've wanted forever!
ShivIka:
* Laagi Na Choote (for some sort of an intense, angsty romantic scene!)
* Zara Zara from RHTDM (for another angsty, romantic rain sequence?!)
RiKara:
* Jashne Bahara (for a reboot of those gorgeous garden scenes from DBO)
* Maahi Ve (for some sort of an insight into Gauri's POV of their love story /ie. like Shivaay's confession video)
RuVya:
* Manchala (for a really, really angsty heartbreaking airport sequence where she's leaving him, and he's running after her! HtP style)
* Nashe Se Chadh Gayi (drunk Bhavya, smitten but at his wit's end Rudra!)
Those were some of mine, and now, you guys shoot!
