Shierlaw, 33, enjoyed a sublime Season Seven in the red, white and black, leading the Saints' goalkicking with 13 and taking out her maiden club champion award.
But while the former Blue remains a beloved name on Nick Dal Santo's roster, love of a higher order could see her make the move to Arden Street, with the prospect of playing alongside her partner, Roos skipper Emma Kearney, a live possibility.
As first reported by Daniel Cherny of CODE Sports, the allure of calling Kearney a partner on and off the field remains a key drawing card, as does a chance to chase a premiership before all is said and done.
Given the regard Sheirlaw is held on Linton Street, a trade of satisfactory proportions will require striking for the Roos to secure the key forward's services.
Ahead of Season Seven, each AFLW captain was polled as to which player from any rival side they would love to recruit with one skipper anonymously stating that Shierlaw's name sat atop their wishlist.
And with these trade winds now whipping, any remaining ambiguity as to who had nominated the Saints' former co-captain has, well and truly, evaporated.
Proficient in the air and in front of goal, Shierlaw's skillset would prove priceless for a North Melbourne team that bowed out on preliminary final weekend, managing just 2.4 from a staggering 36 inside 50s.
Should Kearney's recruiting drive prove successful, Shierlaw would join the ilk of Rhiannon Watt (Melbourne), Catherine Phillips (Essendon) and Tilly Lucas-Rodd (Hawthorn) in departing Moorabbin of late - moves that created a genuine leadership dearth in what is an already understaffed locker room.
Across the course of her AFLW tenure, Shierlaw has laced the boots on 44 occasions; splitting the big sticks 44 times.
