Installing Skyrim DLC as mod.

Ok so i did the mistake to buy skyrim without any dlc.Since none of the dlc is getting sales i started wondering what if i get the dlc i need from somewhere and just install it with NMM.I know it woud work,i just wonder if this will get me banned or reported or whatever...

PS if you are planning to report me now,just now i will do this on a alt acc with family sharing :)
