Was the premise of two sisters marrying father and son unwatchable?

From Indian history, recorded in Kalhaṇa's Rājataraṅgiṇī (Book 8, verses 459-460), we have the example of King Sussala of Kaśmīra, on an expedition of conquest in the years 1111-1112 C.E., marrying Rājalakṣmī, the elder daughter of Chuḍḍā and Garga, while accepting the younger daughter Guṇalekhā as his daughter-in-law.

In the year 2023, we have Sandiip Sikcand's so-called raising-the-bar progressive story Cāśanī, in which Sumer Babbar, a violent conqueror of real estate, marries the younger sister Roshani shortly before accepting the elder sister Chandani as his daughter-in-law.

How does everyone feel about this situation in real life and in fiction?

Was the show Cāśanī doomed by its boring/bold premise, or could it have become as memorable as the Second Lohara Dynasty?
