I'd weigh in here with the Flames Central v. The Palace debacle from the 2000s and 2010s.
The original design of the venue was some sort of Flames sports bar that hosted music. It featured giant screens and flames murals everywhere. Cool if you were a Flames fan - but discouraged artists to book the venue and was confusing to attendees as the market and use case was really just to provide a mid-sized concert venue in a good location. It was way over-designed towards being a strange off-site Flames thing rather than a concert thing.
Eventually (after about 7 years) they recognized that and stripped out all the tacky Flames stuff and converted it to just being a concert venue that it is now, still a bit weird layout due to the misstep of the Flames-based renovation, but at least it's not discouraging audiences and confusing people for what the place is.
The arena should take a similar note - feel free to lean a bit into the local style, but remember it's famously an "event centre" not an arena, nor a stampede venue. It is also famously not owned by the Flames or the Stampede, it isn't paid for by either of those groups, just leased to them for occasional use - it's a city-owned arena that is supposed to be for public use for major events. So add some local design flourishes, but sparingly, and remember this is a billion dollar event venue owned publicly of a city of 1.5 million people with diverse interests and ideas.
