Morrowind Code Patch question

Ive already installed the code patch and a bunch of mods. Everything is almost how I like it.
Can I go back and make changes in MCP, patching the exe again? or is it too late? Theres one thing I`d like to change.
I did a search and couldn`t find the answer. I don`t want to experiment in this case.
Thank you.
