It's not a terrible plan as-is, depending on how you're eating, but you might realize you're having trouble either going full throttle in the HIIT sessions or going at a decent intensity with the GPP.
HIIT is very intense (duh, it's in the name) and can be a lot to handle, especially as the second session of a two-a-day training plan. Combine that with the relatively-high volume of lifting, and it might become too much.
You may want to consider adding a third GPP day on Saturday and turning the HIIT sessions into 15-20 minutes of steady state, moderate-intensity cardio like high incline walking or jump rope (either still as a second daily workout or just tacked on immediately after lifting).
I saw your pictures in your old training log and, unless you've changed drastically in a few months, you don't really need something as intense as two-a-day training sessions just yet.
So either of those changes to the "cardio", plus hard lifting like the WM, plus tightened-up nutrition should get you where you want to go.
