Can I use a Lantern of Shadows at the same time as Blade Hands or alternate forms?

I know that followers of Ashenzari can get the skill benefits of a cursed enhancer staff while still using unarmed attack skill/damage if transformed into an alternate form, so this got me wondering if I could do something similar with the shadow summoning benefits of a Lantern of Shadows while using blade hands or alternate transfiguration forms.
