Actually I have done just that in some of my tanks and it hasn't looked bad or stringy at all.
I got the idea after seeing a little 1gal nanocube that had had a couple of different macroalgaes in it at the LFS
and it looked pretty nice and even a little more "natural".
I just took a ball of cheato and lightly wedged it in some rocks near the back of the tank.
It has stayed in a pretty compact shape and several critters have taken to nibbling on it from time to time.
It certainly looks better than the aquarium that I put an in-tank fuge... now that is butt-ugly.
Of course an HOB
fuge doesn't take too much room and it gives you extra space for some LS
or rubble, but you'd probably need to add some lighting if you want to get the most out of it.
