How to create overlapping Index Grid?

I'm able to create a reasonable index grid using the Grid Index Features tool based on the extent of my study area. What I'm trying to figure out is how to create an index grid that has a percentage of overlap. The following is going to be used to generate a DTM using Topo to Raster . The source is contours for the entire Dar es Salaam at a 1m resolution from surveyed contours. When I last tried to run it using the full contour dataset as a single feature class it ran for 7 days at a 5m resolution.

Index Grid:

Overlapping Index Grid: 10%

DTM: 5m resolution
