Switching ancestral land between siblings. Taxes and costs

Hello, We have an ancestral land in Kerala passed down to us. The land has been split into 2 plots, Mine is around 40 cent & has an old house with land, my sister has 30cent with just land, no house. The aadharam is also split in the same way. We would now like to exchange each others land. My sister will take the 40cents house with land, and i will take the 30 cents. There is no payment involved as i am not taking any money from here or vice versa. Is there any way legally or workaround to prevent taxes or pay minimal tax and change ownership? Considering its ancestral property and so on? FYI, I am a US Citizen and she is an Indian citizen. Is a gift deed or something of that possible? Pls help.
