Bikepacking With A Carbon Bike

I’m looking at doing a decently long bikepacking trip mostly on road. I currently have a carbon framed orbea avant endurance bike. I’d like to do the ride without necessarily buying a new bikepacking bike. I was thinking that a seat post bag, frame bag, top tube bag, and maybe a backpack to ride with and putting 28 or 30 mm tires on. Does this seem reasonable as a setup? I’ve done century rides on this bike before and it’s comfortable enough. What are the drawbacks of a carbon endurance bike vs. a more bikepacking focused steel or aluminum bike? I know if the carbon cracks I’ll be SOL.
