Bad idea unless you have a LP grand and modify it in various ways to accommodate the low Ω
coils you'll want to run in that.
You also have to mod the Helios to bottom feed and make all your
coils at exactly the same resistance, so they don't heat at different rates. Other than that, go for it!
I do use a modded igo-w4 on my LP grand, and the grand has been modded too, since anything under 0.6Ω coil-wise is flirting with trouble. 0.4Ω and you are in spring collapsing territory until the new rebuild kits for Reos come out.
