Gravel bikes as road bikes?

I’ve got a Trek Checkpoint SLR 5, 2x grx chainring done some upgrades now so it’s lighter and stiffer than stock. However, I’m finding myself looking at road bikes. I love the feel of fast road riding in the summer, as much as I love gravel riding there’s something about riding at a really quick pace that I miss. Do I just buy another wheelset to save my wallet and do gravel bikes actually feel good kitted out as a road bike?
