Reach to the levers is a function, primarily, of the lever design. Altering positioning of the levers on the bar can help, and you should probably play with that if you haven't.

Another option is to see if the lever reach is adjustable, a feature which some Shimano levers offer, either through an internal adjustment or addition of a shim. This will move the lever rearward and closer to the bar.

Whether you need more reach to the bar is a separate issue, and one I'll leave alone for now since I don't think it's related and because I'm confused by the numbers you've got going there, anyway.
