[MCU] If Mjolnir wasn't destroyed, could Thor have stopped Thanos by placing it in his open palm?

Would keeping his hand open stop him from using the gauntlet?  Could Thanos somehow lift Mjolnir?

Thanos himself seems to think he needs to do physical gestures to use the stones, though the stones show enough knowledge of his intent that they can clearly pick commands out of his mind if he wants them to.  So pinning his hand probably doesn't stop him forever.  

Which doesn't matter because a fully filled gauntlet is far more powerful that Mjolnir, and would be able to overcome Odin's restrictions.
