It is already possible with viral vectors (in mice). The CREB experiments increase excitability, ltp etc.

the CCR5 receptors (which was modified in chinese human babies) affect plasticity & memory :

it is also possible with optogenetics to gate plasticity, erasing and reenabling memory engrams

its not clear how increased plasticity is beneficial though (these experiments are mainly aiming to erase memories, like PTSD memories)
