22 is on the the threshold of all three the Gourami's min and the Clouds max. The advice that usually given is they're not compatible because neither will be in a comfortable temperature but you could still technically do it successfully.
I don't have sparkling but I do keep a school of long fin white clouds with my Celestial Pearl Danio colony and breeding pair of honey gouramis with their juveniles so I don't see why they couldn't get along with sparkling gouramis temperment wise. As for temperature, I keep the tank at 73 but the summer months may raise as high as 76 or so if it goes beyond that the fan kicks in to cool them down, been two years and everyone's looking happy and healthy. Higher temperatures will increase metabolism and may subsequently shorten the lifespan a little but it doesn't mean they can't handle the higher end of their range or above for periods of time.
