Black Reach to Sternguard

So here's my plan for getting some Sternguard converted up on the cheap.

1. Take a few of those Assault on Black Reach tactical marines. You know you bought the box, it was simply too good of a deal to pass up, and now you have marines-a-plenty. Pick out five.
2. Grab your files and get busy grinding off that stupid "tactical squad" arrow. It just doesn't fit on a Sternguard.
3. Use the two bolters that have scopes attached to them, and then the two bolters that have the slings. Pick a plain one for the fifth.
4. Look in your bits box and find 3 more scopes. You know you have them. They come with every tactical marine frame.
5. Attach the scopes to the bolters that don't have them.
6. Voila! 5-man basic Sternguard squad, ready to go. Prime and paint, not forgetting to use white paint on the helmets and shoulder pad trim (or whatever your chapter color scheme for vets).

What do you guys think? I've already made 4...
