To my fellow Khasi and Jaintia brothers and sisters. How do you feel about Bodo-Garo/Kachari people ?

Context: Ancestors of Khasis and Jaintias as far my as knowledge were widespread in Assam's Brahmaputra valley (both lower and upper assam). When Kacharis (linguistically called Bodo-Garo) arrived in Assam they intermixed intensively with Khasis/ancestral Khasis, leading to complete absorption of Assam's khasi population into Kachari tribes whereas many Khasis moved to present day meghalaya. (MY KNOWLEDGE IS VERY BASIC IN THIS REGARD, SO ANYONE WITH FURTHER KNOWLEDGE CAN JOIN IN TO CORRECT). This is also one of the reasons why modern Kacharis of Assam/Tripura/Meghalaya (Bodos, Dimasas, Tiprasas, Garo, Deori, Moran, Sutiya, Tiwa etc) look slightly less mongoloid than other hills tribes like Nagas, Arunachalis, Mizos etc whose ancestors did not intermix much with ancestral Khasis. Now coming to my question, if you come to understand blood relation between Khasis and Kachari people because of historical circumstances, would you feel increased sense of brotherhood with the Kachari people? (I know Garos already reside in Meghalaya).
