Worth converting cooling system

Recently me MJ will overheat in low speed and hot driving. Doesnt happen very often so I really dont see it as a problem. And if I run the electric fan it keeps it under control.

When replacing my belt today I noticed that theres some places on my radiator that are rotted. Some are bad, but its mostly solid. When I go to replace it, would it be worthwhile to convert to the open system?

(1990 MJ 4.0)

The main cost is the radiator. I'd look at a Modine or DPG http://www.dpgoffroad.com/
Also look at the Mad XJ article and Cherokee America has a good article. If you look at the links on the Cherokee America's article they have a setup for the temp switch.
