Whoa - that scares me, and I don't scare easily!
Here's what I'm thinking...
First of all, there's no way in the world to make that completely safe. Period. But since you're a guy, and you want to do it, you'll do it anyway.
Therefore, the need is to minimize risk.
One thing I see is that the arbor in the blade is larger than the shaft of your weedeater. You're going to need a sleeve shim, and it's going to have to be a precise fit, or the blade is going to be terribly out of balance. It looks like you're also going to need a reverse-thread lock-nut. A hardware store is probably your best bet for that stuff, but it's a long-shot.
Keep in mind that those weedeaters spin at a VERY high rpm. If anything goes wrong, it's probably going to go wrong in a big - and very painful - way.
