I dunno, Kineticist seems like the easiest to port over. A lot of its class features already resemble the class feat system present in the new system.
I would say that Kineticist should resemble more of the Warlock class. A blast-centric class with an at-will and exclusive occult cantrip that is their Kinetic Blast. Uses only a Somatic Component for action economy reasons so they can make more attacks as their accuracy goes up.
Maybe nixing Burn in all but name. Restructuring it around a Focus Point system based on the Proficiency Modifier + Constitution Modifier. That to recover these Focus Points requires [X] Hours of Rest/Meditation.
To account for Utility Talents and Infusions, maybe have the FP Cost be 0 but can be increased to provide a bigger and more impactful benefit.
Like for example with Kinetic Healer at 0 FP providing [Y] Temp HP. But actually investing [Z] FP into it instead allows the Kineticist to actually heal HP damage based on the would-be damage of their Kinetic Blast cantrip.
