Help editing a hairstyle's physics please

[valencia]

So there's this mod called Daemon Girl on the nexus and it's basically an outfit mod to make your character look like Daemon girl or Succubus Sinia which is very nice and I highly recommend it if you wanna roleplay as a succubus. The outfit is composed of horns, hair, bikini, stockings, heels, sleeves for both uunp and bhunp. Personally I use the AIO 3bbb smp for le package that is found here on loverslab and I have already converted the outfit to this body with no problem. However, for some reason every time I equip the hair my fps literally goes down by legit 10 sometimes even 15 because it has smp physics to it. I did not touch the hair only the outfit. I run smp on my pc with no problems. and I convert outfits that I like to this 3bbb smp body mod with no fps drops at all. It's just this hair's physics is nuking my fps. I tried to move the xml file that is related to the hair someplace else to completely disable its physics but the hairstyle then looks like a giant broom. Very messy which tells me it was designed to be animated from the start. 

 

So is there a way to make the physics on this hair, hdt pe instead of smp? Or if it's not possible can someone please tell me how to edit the hair in outfit studio to sort of like trim its length on the side and the bottom? Here's the hair and the xml related file. I do have the havok tool modifier and nifscope if it requires work on them but would need instructions on what to do. Thanks in advance.
