I stay away from core modification at all costs. Every upgrade to XOOPS there after will be affected and you may have to reapply your core changes each time. They may or may not always work, depending on the development cycle of the module developer. In short, I don't advise using modules of this nature. Although many people have had (limited) success and feel comfortable with applying core changes.
Before you upload the files to your server, compare the files (outside) of the module folders and make copies of them FIRST.
If your conversion works, great, if you have user problems, you can always replace your files with little effort.
I have in the past used mods that modify the core files. Sometimes this breaks your system. Proper preparation is in order before using these types of modules.
