Here's an idea for a new connecting line around the north of the town, ~7.75km in length, partly using former trackbed of the Ashby and Nuneaton, with a new bridge flying over the WCML:

Nice idea but expensive and a few problems.
The section between the Nuneaton to Leicester line and the first crossing of the A5 is currently being turned into 3-4 big distribution centres, section after A5 Is shortly going to be an extension to Dobwalls industrial estate.
The section near to Nuneaton down the old Ashby line is my running route so leave alone!!
