Partition Suit to intestate death

Have fought a simple Partition Suit of my father's (died intestate in September, 2004, mother pre-deceased him in 2002) self-acquired property in Bangalore city civil court. Five undisputed coparceners (3 brothers and 2 sisters). Father has written a letter to one of the sons (residing in USA, in Oct, 2003) regarding his opinion/offer for distribution among his children in the ratio (12.5% to 2 daughters in equal share and remaining 87.5% to 3 sons in equal share). One of the Issues made by the court was to decide on number of partitions and the quantum to each partition. The trial court judgment in November, 2017 has declared equal share to all coparceners. Inspite of argument presented by two plaintiffs that Supreme Court interim/guideline ruling in civil appeal case #7217/2013 (Prakash Vs Phulavati) declaring daughters as coparceners only if father was alive on the day of HSA amendment 39 dated 09, Sept, 2005, the Hon’ble trail court awarded same quantum to all 5 coparceners. Do I have a strong case to appeal in KA High court? Please provide detailed justification if the answer is YES or NO. Thank you for time and appreciate your answer in advance.
