Yes, the water is to make it dissolve better. Your idea doesn't sound like a bad one, and it's probably worth a shot. The only thing is, I've never done that, and have no experience with how boiled yeast turns out, but I've heard stories of new brewers pitching the yeast *before* boiling, and then pitching more after learning of their mistake, but I've never heard of the yeast imparting a bad taste as a result. Yeah, it will kill all the yeast, but as long as you just boil a portion of it, there's enough viable yeast still in the fermentor to do everything you need.
So I see no reason to try it... just make sure that the portion of beer you'll be boiling is pretty clear... boiling a bit of suspended yeast shouldn't be a problem, but I wouldn't risk it with a beer that's completely cloudy with yeast. And don't boil it for too long... even a minute should suffice.
But other than my uncertainty with the yeast thing, it's a fantastic idea to use beer instead of water in order to maximize the added gravity (by not further diluting it). And make sure you are very sanitary when taking out the portion of beer you're adding the LME to... you may be boiling that portion, but you're obviously still going to touch the rest of the beer in the process of taking some out.
