In time, yes. There’ll be Bears holdouts who will never support the club, but it will be about getting the next generation interested and invested in RL and the club. In 50 years time, the Bears will be forgotten about almost entirely (unless they win an expansion slot in QLD, NZ etc of course), those rusted-on Bears fans mostly won’t be around to complain about the Sea Eagles anymore and it will become a given that the North Shore is the territory of another club now.
Starting the push in the area from the base of an established club, that has both a strong identity and history plus brand recognition with kids, is a far better proposal than starting with a new plastic club and brand. A new brand wouldn’t mean anything to anyone and would have to re-win the support of the Sea Eagles fans and start pushing back into the North Shore too. It makes no sense whatsoever to make things harder and more complicated by trying to fight on two fronts when only one is necessary.
We’re not talking about a brand new expansion region here, it doesn’t need a new brand. It’s a region of Sydney that needs proper engagement and attention from an existing NRL club. It also doesn’t necessarily have to be Manly, if that’s your bugbear, it could be Manly, the Roosters or a split between them, it just needs to be an established NRL club.
The name ‘Manly‘ is part of the team’s identity, it’s how we’re commonly known and how we’re referred to in shorthand. It should ideally stay, that’s why I said a far more acceptable proposal would be to drop Warringah from the club’s name and be known as something like ‘Manly-North Sydney’ or ‘Manly-North Shore’ instead of ‘Manly-Warringah’. You can acknowledge both regions with a name like that, keep the Manly identity and ability to call the club Manly in shorthand intact.
