Hi Straus, day trip from Inle Lake to Kakku is perfect. About the itinerary for 2 people, I suggest this: 
– Begin with Inle Lake toward Taunggyi, then head into the rolling hills toward the east of the lake. The drive is spectacular, crossing over the railway line and through small villages inhabited to the Pa-Oh people. 
– After two hours you’ll arrive at Kakku. The first view of Kakku is breathtaking: there are more than 5200 individual stupas, some of which are 20 metres high, and several Buddha images scattered throughout. There are no clear facts about the history of the stupas but most date back to the 11th-13th century, the same period when Bagan was thriving. 
Wander throughout the temples, taking your time to enjoy the wonder and awe of this site and discover the intricate carvings and details on the structures.
In addition to visiting the temples, Discovey Indochina’s guide will introduce you to the customs and lives of the people as you stop to visit nearby villages.
Afterwards we will have lunch at a local restaurant near Kakku train station and then resume our drive back to Inle Lake.  (L)
