I think it looks great - but no way you could have a Magpie logo on there.Why wouldn’t port use something like this?
It’s classic.
Looks good.
Has history but with teal.

No problem with teams sharing colours, but there can only be one 'Magpies' (or any other mascot) in a league.
Edit: Thought this was an AFL suggestion - for SANFL of course the Magpie logo is fine
