[Request] - Mesh Edit for a Mohawk Hairstyle

Hello! I stumbled across Holy/Hell hair by Slythersim and immediately fell in love with the style, but was wishing the hair tuff portion could be tweaked a bit. Since there weren't any mentions about mesh edits on Slythersim's ToS page, I sent an ask their way and was able to get the greenlight, just as long as the edited version relies on the original to function. 


The changes I'm interested in:

• thinner / narrowed hair tuff on top
  
• hair tuff to be slightly pushed up so it starts closer to the hairline
• more voluminous in size
• expanded to be longer, so instead of just being on top, it trails all the way down to the neck

Here's a messy edit I did to help provide a better visual:





In the past I've done recolors, mods, etc., but each time I've tried my hand at Blender it all just becomes a big mess. :(
If anyone was interested in making this hair edit a reality, it would be immensely appreciated!!
