Don't try to invent the wheel. Give that Lego back to the kids.
The great paperclip already exists, so use it!
Take a big size paperclip and bend it, and you're done.
See the pics (a blue wallet is used for demonstrating).
I'm using this great x10 stand at my desk at work and also at home next to bed.
Hahaha! Well I'm 36 years old. At times when my son can't figure out how to build his Lego I like to help him. Lego is cool! When I was young I didn't have a cellphone, so I build the Transformers!
Maybe you can adapt your lego stand, so you can adjust the angle or make it easy to lay it landscape or portrait. Maybe you can also build some sort of 'roof', so you won't be hindered by sunlight when watching movies.
Keep it up!
