I wouldn't change the structure. Purify the codebase into pristine 2003 php, with a sane toolset. You'll learn all the quirks of the problem code as you do this.
When you've got a clean base, the team will be moving quicker, be more skilled with what they already are learning and listen to you. Then you can consider the structural changes.
Pure, clean 2003 php into a new format is way easier than spaghetti nightmare into total re-write.
