Hiking Trail that connects the hills around Kathmandu valley!

Kathmandu is a valley (Kathmandu, Bhaktapur, Patan), which means, it is surrounded by hills. I was wondering if there is a trail that connects each hill.

I want to know this because I want to hike the whole circuit.
It will be my valley circuit hike odyssey.
If there is no such trail what should I do to put it on the map?

I have even thought of the name of the trail Manjushree trail. There is the pacific crest trail, AP trail and here we do have GHT but I want a trail that touches all the 3 districts (Kathmandu, Bhaktapur, Patan).

I am willing to camp if I have to to complete this trail.

Please let me know This could possibly be a route.
I found it scrounging maps of Kathmandu * = possible site to camp or resupply stocks Kakani
