Here are a 2 cool tricks tgat I have found. The build on display is not suposed to look good, it's just to show of these tricks.
You can useuse Ferno's head up-side-down to have a small version of the mask of shadows... kind of.
You can also use the skull spiders as shoulder pads (but some of the other masks are to loose to be used.)
So those are 2 tricks I have found out about. If you have any you want to share, this is the place to do that.
