You should read their FAQ, as one thing they mention is that they're only swappable between wheels/tires with the same diameter
and the same width, which could be an issue for your application. My guess is that being plastic, they mold to the shape of the rim/tire combination they're installed in and don't return to their original shape the way rubber tubes do. Assuming that's the case, it means that once you use them in a 40mm gravel tire, you're not going to be able to stuff them into a 25-30mm road tire.That means you'll need at least two sets of them, which pushes their already exorbitant cost into the $140-$150 dollar range. At that point, I'd stick with rubber tubes and start saving for a second set of wheels that I could run tubeless.
Perhaps they would work if you restrict yourself to relatively narrow 32-33mm 'cross tires off-road and relatively fat 30-32mm road tires, but assuming that you already have tires, that just adds more to the cost, pushing it into the $200 - $300+ range. It's also unclear how well they handle repeated changes.
Frankly, a second set of wheels looks like a much better solution for you and it's also a lot more convenient. Although I literally changed thousands of tires when I was in the bike biz and I can do it quickly, I wouldn't want to do it on a regular basis, every time I want to do a different type of ride. Additionally, multiple changes can be hard on the tire beads, particularly for tight-fitting tires.
Note also that sealant doesn't work with Tubolitos, which means that if you live in an area where thorns are an issue, you're likely to end up doing a fair amount of patching. They may be more puncture
resistant, but they're not puncture
proof.
