Full Body and FSL/Jokers

i have been using 5/3/1 for the past 4 months, but after recently becoming a father i am reducing training days to 3 days instead of 4.
i am going to use the full body training template from the Beyond 5/3/1 but i am unsure if there is room for FSL or jokers in this? would it be too much volume in the week?
has anyone tried this with success?

Thanks

No FSL. Jokers every 6th week.
