On a key of "C" chromatic, you would play what I call the "Little Walter 3rd Position Style". This puts you in the key of "D" or more correctly "D" minor (blues scales and minor scales have much commonality).Like 3rd Position on the diatonic, most of your strong notes are draw notes. Since you are in the key of "D" (actually D minor), your resolution is on holes 1, 5, and 9 draw. Use the blow notes more as passing tones versus holding them for long periods.
The vast majority of 3rd Position on chromatic is played by tongue blocking and using the specific tongue blocking techniques of "Delayed Tongue", "Octaves", and "Tongue Tremolo"-

Scale-
5D 6B 6D 7B 7D 8B 9D
(you may want to leave out the 6B and you can also go below 5D by using 4B and 3D)
Listen closely to some of the classic Little Walter stuff or any of his followers. If you can tongue block reasonably well, you will find it very doable (at least to get you in the ball park).
Play on,
