I expect that was the idea. I've heard Uveto was supposed to be the introduction to Psionics, but that didn't really go anywhere. I've also heard they never really had a firm idea of how Psionics was going to work. Whether it would be a base Class or something you'd acquire later, possibly with some kind of parasite/symbiote.
A potential problem with Psi-amps I foresee is it taking up the Accessory slot. Other classes don't have a required Accessory. The closest is Drone Techs and maybe Melee Techs and Smugglers (Light Jetpack), though you can get around that with Wings.
