Underwhelming, but yeah that would be the most straightforward conversion with the least re-writing. Something you'll find is that Edge gain rates and utility of Edge are highly dependent on a character's role.
Most all Edge gain happens on opposed tests, so if you're a combat character or decker, you have a lot of Edge gain opportunity. Combat characters have the most opportunity, because even if they are outmatched, it's feasible to create situational or environmental conditions that would give you Edge with a little creativity. Deckers are feast-or-famine. Almost every roll they make is opposed, and the DR of their opposition rarely changes (everything in a network defends with the same stats) so they will either get Edge on every roll, or none. But unlike regular combat, there's not really opportunity to turn the tables with creative situational advantage. If they take Analytical Mind, (we ban it at our table) they will get Edge on every roll besides perception. Mages get surprisingly little Edge. Spells against opponents will get edge opportunity, and spells can be good at creating circumstantial Edge situations. Spirits can't gain or use Edge though, and conjuring them only grants Edge if you have a particular quality or burn money with reagents. Street Wyrd adds the Shamanic Mask quality, which I think is a terrific, well balanced Edge gain quality and it should just be standard on every magician without need of a quality. Basically "Make your magic obvious to gain Edge". Good tradeoff.
Edge is also most useful in opposed tests. 1 Edge is better spent rerolling your opponent's hit than rerolling your own failure. The four and five Edge moves are the most useful for non opposed tests. So if you're an archetype that isn't always making opposed rolls, you'll be getting less Edge and getting less utility out of your Edge expenditure. That's a generalization, but yeah. Deckers probably get the best mileage out of their Edge use because in addition to rerolling opponent successes being the most efficient use of 1 Edge, every success-turned-failure in this way is also 1 less point added to Overwatch Score.
