Scar removal with vertical and serial excision? (Photo)

Hallo i have a 1 inch surgery scar with stitch tracks on the back of my neck. I want to remove it via vertical and serial excision. My idea is to excise, like in the second picture described, vertical in oder to shorten the scar. I would have after the first step a double-cross scar.In the next step i would do serial excision, in order to excise the stitch tracks and the two new vertical scars.Is this idea possible? With this i should get rid of the stich tracks and the scar should be shortened
