Just thinking about a combined XI for the series, it's hard to nail down because some of the top performers for the series hold the same spots in their respective XI's. Maybe something like:
Lees, Bairstow, Pope, Root, Mitchell, Stokes, Blundell, Potts, Boult, Anderson, Leach
That tail is nightmare fuel, but with the amount of runs in 2-7 I don't suppose it matters. Tough on Jonny as well probably, but you can't leave either player out, nor can you justify batting one of them at 3 given how poor the openers were, and Mitchell had a nigh perfect series with the bat.
