The Tigers are poised to land the duo on seven-year deals following their preference to head to Punt Road in what is seen to be an imminent double coup for the Tigers.
GWS are understood to be demanding a pair of first-round picks for Taranto's services as his contract comes to an end, while Hopper, who is contracted, is reported to require a similar asking price from the Giants, according to The Herald Sun.
The Tigers are equipped with Picks 12, 19 and 30 at this year's draft, while holding their own future first-round selection for the 2023 National Draft.
Should the Giants see Pick 19 - the first selection of the second round - to hold enough value to be included as a first-round pick, the Tigers will still need to acquire another top selection to meet the Giants' demands.
Fringe players Ivan Soldo and Riley Collier-Dawkins have been flagged as potential 'sweeteners' for a trade deal between the Tigers and Giants, but more draft assets may be required to get a deal over the line.
The Giants have managed to gain similar trade packages for past departing stars, like Dylan Shiel and Adam Treloar, who joined Essendon and Collingwood respectively on deals that saw a pair of first-round picks head to GWS.
The Giants' stance will mean the Tigers need to get creative this off-season, potentially parting with key personnel or multiple draft selections to land another first-round pick.
Brisbane are one club that will be willing to part ways with their opening selection as they look to acquire enough draft points to secure the services of top prospect Will Ashcroft and potential top 20 selection Jaspa Fletcher through the father-son draft mechanism.
Yet to exit the finals, Brisbane will land a selection ranging from Pick 15-18, which will eventually be pushed back a selection or two given the potential father-son bids from Brisbane and Essendon, who have Alwyn Davey Jnr. tied to their club.
Should they get their way, the Giants will carry a monster draft hand this year as they add to their current top selection at Pick 3, while trades for Bobby Hill and Tanner Bruhn are also likely to land them selections in the first two rounds.
