Is it possible to run an effective Han with only 52 points? Any suggestions please!

You could go with:

Han Solo, Millenium Falcon, Lone Wolf and Kyle Katarn. You can choose to reroll all or only one dice, you can have an evade token, and Kyle helps against Rebel Captive/Tactician.

Or:

Replace Lone Wolf with Expert Handling. You can then barrel roll to escape arcs, and dropping the stress activates Kyle Katarn.

For 3 points C3PO is much more valuable than Kyla Katarn IMO.

Depends largely whats flying with him. Two suggestions:

Tanky Han

Han, Determination, recce spec, jan ors

Two tokens a turn and avoids nasty crits like PS0

Fast Han

Han, VI, engine, MF title

Move last, boost or evade as required, and focus or tgt lock if there's no return fire.
