anyone use great stuff, and rubber gloves for corpse hands???

To finish my FCG I need to make some hands and wanted something with a corpse flair. I use rubber gloved in the garage when changing oil, staining, painting etc. I got to thinking last night, could you spray some great stuff foam in the gloves, let it set a while, come back form the curve in the hands, let it dry the rest of the way and then cut the rubber glove from the foam??

Anyone every try this or have an idea if it might work? I have not used the great stuff before so I was unsure how it works etc.
