Mod an existing mod?

[War4Peace]

Hey guys! I've been playing FFT since its release but I'm new to modding and was wondering if I could start with an existing mod and make small changes to that one for personal use or would I have to start from the ground up? Thanks!

As long as the modder hasn't set up the release version to block the modding tools such as the Patcher, sure. The current Jot5 release is still openly editable last I checked, as an example.
