Yes, but the difference between a sword stab and a sticky bomb is that you can get hit with a sword in a way that just wounds you without killing you. If a sticky bomb like that gets stuck to your flesh, you're losing a limb at least, and you're probably dead. Just look at the Halo plasma grenade. There's a difference between "can kill you" and "will kill you." One of Taylor's icicles can kill you, and getting hit with one wouldn't feel good. A sticky bomb will kill you and there's not much you can do about it. That's all. 

But if you're willing to make those changes, then the character is probably good. Edit the new weaknesses in and you should be good. In the end, though, it all comes down to Allen's judgement, not mine.
