Yes bro it can be great route
Direct like
Sadalpur - malsisar/mandawa - jhunjhunu - udaipurwati - sri madhopur - rings ( it will bypass sikar )
And jhunjhunu , udaipurwati can get direct long route train
But...
more... this one not going to happen in upcoming 50 years if people didn't pressurise govt and MPs of jhunjhunu and sikar as well
