You should definitely do it. I just did (only one brew so far) and it worked out amazingly. I used a hop spider (and bag) to contain the pellet hops so I wouldn't clog the plate chiller. I am also using a 20g pot. You'll need a valve on the return port also (so you can close it when the water/wort level is higher than where the port is). It took a little experimentation to angle the tubing so that it would make a nice whirlpool motion.
here's the setup.
I'm using a side-pickup tube to avoid the resulting cone of trub. The return port goes to an elbow that (currently) has a camlock with a short piece of silicone tubing. This allows me to adjust the whirlpool a little bit to make sure it gets spinning. I may make this a permanent setup, but i'll need a few more brews before I really know. The tubing actually follows the curve of the pot a little better than it looks here.
I run it out of the bottom valve, through the pump, through the plate chiller, then back into the return port. After it is ready, I put the output of the chiller straight into the fermenters.
Like I said, I've only brewed with this setup once, about a week ago, so it may run into problems later, but so far I haven't had any trouble.
