Whoever you are, I love you for asking this.
Here’s what it looks like I think (and this is speculation, I haven’t seen any camp practices in person):
Heavy Nickel
Ninkovich-Kelly-Wilfork-Jones
Mayo-Hightower
Talib-Arrington-Dennard
McCourty-A. Wilson
Rush Nickel
Ninkovich-Wilfork-Benard-Jones
Collins-Mayo
Talib-Arrington-Dennard
McCourty-A. Wilson
Dime
Ninkovich-Wilfork-Jones-Benard
Mayo
Talib-Arrington-Dennard
McCourty-Gregory-A.Wilson
Of course there are plenty of variations around these, depends on what you’re looking for. My concern areas is again having Wilfork extensively in sub, ideally Armstead comes back and could be a viable dime option. Kelly is viable rotation option for Wilfork in any of the subpackages as well.
Otherwise I think Collins, Gregory, Tavon Wilson, and even Logan Ryan could be involved in sub in some capacity depending on the match-up. Perhaps the greatest depth chart question on defense right now is between Gregory and Tavon.
