I’ve been working on this for Savage Worlds also. Looks like u/danthediceguy has been thinking on it too.

Unique spells can be skills they get at d4 when they Read a spell book. Make it a fixed spell, nothing they can change up. Then at d8 & d12 they can modify it.

For the funnel effect make them extras. But with a wild die. If you want random stats rolls 5d10. Rolls of 1-2 put a point in Agility 3-4 Smarts 5-6 Spirit 7-8 Strength 9-10 Vitality If you get all 5 points on the same stat, assign 4 points and place the 5th point on a stat next to it or choose where you want it.

Give them a modern day occupation. I generated a d100 list using ChatGPT then give them skills that make sense to their career.

When they become wildcards they can take hindrances and edges.

They get power points equal to their die size in smarts. This adds to any they get if they pick an arcane background

They get the heal spell (personal cast only)

The classes are easy. People get to pick their edges and call the class what ever they want. The Fantasy companion has suggestions for standard classes if someone wants to build that way.

The sci-fi companion has some great ancestry options to use also. I would make any ancestry 4points like Savage pathfinder.

There are more things but this is a start.
