1000% I want this as well.
I think after she saves him from the Amrutha pregnancy trap, he may realize his feelings for her.
I want him to find out she's a married only after that and think that her husband is in Kholapur. Or if Pallavi's Aai sets her up with a man, RR assumes that it is her husband Mandar.
I like this idea even more. We know that her Ayi won't give up on finding her a life partner and maybe she will be engaged to someone which will not go down well with Raghav.
