I don't think that will ever happened though. 
Raghav knows that Kirti can't function with Sunny and that she only cares about their love story. 
Also, don't you think it's a little bit hypocritical on Raghav side. When he was being destructive without Pallavi by his side, he is trying to separate Kirti from Sunny? 
I remember discussing it on forum somewhere, when Sunny was just introduced.
In initial episodes, Raghav is shown finding rich guys for Kirti. Raghav sees Kirti with Akash and loses his calm. He follows him to D house and then trashes him. Both of these actions were wrong on Raghav's part. Firstly, he is finding rishtas for Kirti, without her consent, consent chhodo bataya bhi nahi usko. Shadi Kirti ko karni hai so uski marzi honi chahiye ki vo kab karegi, kisse karegi. Raghav didn't bother asking ki uski life me koi hai ya nahi, ya usko kaisa ladka chahiye. Akash ke time pe usko MU hua ki they are having an affair, nahi tha, we know, but at least bother asking. But Raghav ji usko 4 language me dhamki de ke aa jaate hai. Aise situation me Kirti will be afraid to introduce Sunny. Plus they were kind off shown as long distance relationship, so vo aise hi thodi introduce karwa sakti hai. Also story POV se Kirti was struggling financially, uski Amma bimar pad gayi (blood-donation scene) aise me bf ko introduce karwana would have been inappropriate.
Second part tab aata hai, when Sunny is shown having grey shade. Yaha par bhi humne discuss kiya tha, ki Aai had told Raghav, "kya tum apni behen ki shadi apne jaise ladke ke sath hone doge" so Raghav ka kya reaction hoga. But again didn't got explored it more.
After Raghav prevent the eloping for the first time, he realizes that he can cage Kirti but not her feelings. Amma usko samjhati hai ki Kirti apni galti se hi seekhegi. As elders and family unka farz tha apna opinion and viewpoint rakhane ka, jo unhone kiya, aage uski marzi. At this point of story, I want Raghav to say "Kirti tum ko jaha jaana hai vaha jao, jiske saath shadi karni hai karo, bas mujhe Amma and Pallavi ko apne games me mat leke aao. Hum tum se pyar karte hai aur karte rehenge."
