Not really, though plenty of people do it. Just think that if you're in a tight group or paceline and something goes wrong (a squirrel goes into someone's wheel, a rim cracks, someone messes up and overlaps the front wheel, etc.), those bars potentially become spears to jab someone else in the event of a pile-up. Most people who don't do triathlon never take aero bars in a group. Many triathletes I know still won't take their aero setup on a group ride, but not everyone has 2 bikes. It's just not a good idea.

Also, a lot of people who put clip on bars on their bike for a TT need to adjust the saddle position to get into a good position on the bars. Often, it's ideal to move down a bike size for a TT setup, because you need a shorter top tube (why TT bikes generally have shorter top tubes built in to their geometry, though depending on your road bike setup and reach, you may still want to go down a size, ideally). So, chances are you're either going to be too far forward (and maybe too high too) for 99% of your riding, or you're going to be even less stable in the aerobars, because your elbows would be too far in front of you instead of dropping more or less straight down under your shoulders. Maybe if your lower back is extremely flexible, you can make it work better. Then you might be so low and straight with your back that it's hard to look up the road.

If you aren't doing tris or TTs, there's really no need to use aerobars, especially in a group. If you want to try to get more aerodynamic on your road bike out solo, then put your hands on the tops close to the stem, bend your elbows close to your sides, and crouch down. Or get in the drops to make it easier to put out more power, and as long as you don't have bars that are too wide for you, you'll be relatively aero. Shave off resistance by using better wheels, putting a bottle on the seat tube only, or going without gloves. Really, though, does any of that REALLY matter if you aren't racing against the clock?

I vote no aerobars on a group ride ever, unless you're practicing for a TTT.
