To improve EIGRP convergence time, you can work and manipulate with Feasible Successors, EIGRP Query process, Load balancing etc. I will go through each of them shortly, just to give you hint what parts of the EIGRP can be touched to improve convergence.
By having Feasible Successors all the time
You can have situations, wehre you don't have Feasible successor Routes. An alternate Route to desired destination may present but EIGRP has simply rejected because its Reported Distance (RD) is greater than Feasible Distance (FD) in order to avoid potential loops.
