Idea, Michailo-Dianow “Never give up” Can I build it 
Using parts from the MB box “danger close” , I think so
first steps, cutting and glue some parts in the position
For the fingers using Tamiya glue to get them soft than bend them in position,
for single fingers, it depends to the direction of you cut or saw them apart.
You can also use the glue to soften them for better cutting. Don’t overdo it with the glue.
The cup is just a sprue cutting to the right size and drill out
