You could. Honestly, one of my friends is doing it. The main problem I see is competitions and practices on the same day and same time or something crazy like they're competting against each other. It would be easier if it was the same gym or near your other gym. It's possible but it can be stressful going back and forth and it may cost more. You shouldn't worry about what others think of you. If it's something your really want to do, will be able to do, and think you can handle the extra load of pressure, go for it. You could get more advanced and go to Worlds and such. I REALLY Hope This Helped!(: xx
If the teams are at the same gym then yes, you can cross over, I have done it. But most of the industry does frown upon it. If the teams are from two different gyms then most of the time you are not allowed to do that especially if one team goes to Worlds because there is a form you need to sign.
If they are at the same gym you could be a cross over for another team but if its a different gym then practices could be on the same day.
You could try but people might call you a cheer whore and most likely practices would over lap and cause issues so i would say no.
yes you would just not go to that one and go to worlds probably but its ok I cheered on three teams two years ago but now I cheer on just two because I broke my foot in tumbling
