imho, full body workouts or splits should not be mixed.
The usual goal of the split is to tax your muscle group (chest, arms, legs, etc.) so hard that it needs several days to recover, until you hit it again with a slightly higher intensity. The goal of the full body workout is to tax every muscle group without annihilating anything, so that you can do it again within a short time-frame.
Beyond that it's tough to give you advice, you've not posted anything re: your program and goals. The prevailing wisdom is that FBs are great for beginners, but at an advanced level, your muscles, tendons, joints, etc. are sufficiently developed to handle the intensity required to reap benefits from a split.
