The apparent boldness of the diplomatic solution was in fact the only chance at getting the first foothold in the Great game( with the Russian empire). At the time of Maharaja Ranjit Singh's zenith the British as well as the Sikhs did not go into conflict (the Sikhs had a well oiled army and a stable administration governing), so the question of placating the Sikhs doesn't arise. However the Sikh tacit support was needed as the British primarily wanted to have a say in the political sphere in Afghanistan in order to prevent Russian advances whereas Ranjit Singh wanted to maintain his empire without ceding space to Dost Mohammad or the tribes.
The reason behind William Burnes failure to strike a deal is due to his inability to convince Lord Auckland. This compounded by the tripartite treaty led to the disaster that followed. Therefore this diplomatic solution was to develop a stronger bond with the Afghans rather than placating both the Sikhs and the Afghans and in hindsight would possibly have been successful but for the unknown reasons as to why Lord Auckland didn't approve of it.
