The problem with that is that Lambda's range is so much greater than Hakumen's. If you can get her near the corner, you might be able to do that. But again, Lambda's range is greater than Hakumen's so if he is within his range, she is within hers. She wouldn't be at her optimal range, but her decisions could easily put Hakumen in a bad position and might be too quick to react to.
What range do you think Hakumen would want to be at?
