You'd need to work with profiles twice as thick... a 10% for where you want the 5%, 16% for the 8%, etc.
I was wondering about the utility of such thin airfoils.
And use only the symmetrical series.
The semi-symmetrical 4-digits arch the camber line above the chord line, so a split along the chord line would give a totally different shape than using the symmetrical series.
