This is really more of a question for your local group, as they might have traditions (or in rare instances, even rules) that stipulate who should use shields of that shape. Nationally, you can use whatever you want and no one will be too offended.
Now, some groups might say "oh, he's using a heater shield, well, we don't like people who aren't knights to do that, so we would take that into account if he ever wanted to become a knight in our group." But no one is going to give you too hard a time, or even notice, probably.
