Not for a beginner. This would require a large cage, a very experienced keeper, a very high level of understanding the individual animals behavior, and a lot of free time. The animals can show such small signs of stress that the keeper may not notice until it is too late for one or both of the animals. Even with experienced keepers it can happen. Plus there is no way to ensure that they will get along or one won't dominate the other and not allow it to bask/eat and what not.
It's just not worth it if you care about the animals.
