How to make your legs invisible?

[NicoFilippo]

Wow, what a weird title? Why would you want such a thing? But yes! I need my sim to have invisible legs!

Why? I gave my sim Grim Reaper trait (testingcheats on + traits.equip_trait GrimReaper) and I want him to have no legs, because Grim Reaper doesn't have legs. I have s4pe installed, but I don't know how to use it! And again - Why? I wanna have fun, but also I am Sims 4 blogger, and I wanna make a little blog about it. I started it, but got stuck here!

I am pretty sure there is no way to do this. Maybe, if you want to play Grim yuo could kill a sim, wait for Grim to appear and then using 'testingcheats on' 'shift right click' him and use 'add to family'.
If you do add Grim to your household, do not take that household into CAS or Grim will lose his ability to float.
