As for how it performs, it largely depends in the tire width and psi you want to run at. Too high a psi or too narrow a tire isn't great for tubeless as the psi may be higher than what many rims are designed to handle an/or psi too high makes it difficult for sealant to work.
Again, all generalizations.
Details matter, so your situation may work or not, depending.
I may just carry a spare tube and patches.
