I'm not sure you appreciate how much work it is to both "write a detailed spec" and then also to "write a more modern client".
All of that on top of a system which has likely changed in the intermediate years. Basically, you might as well milk the existing system for as long as possible and then replace it with a completely new system that probably runs on newer hardware (1990s instead of 1980s), is much more maintainable and does things in a more modern way.
For that type of project, it might be worth it to write a detailed spec for how the back-end talks to the front-end so in the future it's possible to write a more modern client.
