It's possible. However, that depends on how their powers branch out. For example, if a Gemstone is indeed a Electromaster, they may discover their abilities as something like manipulating electricity alone. However, as they mature in their age, new powers can branch out from their ability to manipulate electricity alone, like making EMP, magnetism, and fire. What makes them unique is that their new ability can be managed either voluntarily on involuntary.

As for artificial espers like Misaka, the only way they have to learn new abilities is apply knowledge in what they can manage and what can they provide for the ability they can manage. Like, when Misaka was young, she can only manage large volts of electricity, but when she grew up and maintained her physique to provide control of her powers, she can manipulate tons of electricity that can be able to produce a Railgun. Even Accelerator is the same, however with unorthodox methods like how he went during the Dark May Project.
