Imo, wouldn't fit Valorant (or VCT's rather) overall aesthetic. Compare it to League of Legends, where even with the MSI and Worlds branding either leaning towards the grunge or regal, League has always been more of a "gentleman's affair" presentation, but that doesn't mean they shy away from a more casual look either; just look at their Tier 2/Academy League/Regional Leagues broadcast.
However, the VCT has always been more of a tech, grounded, and even more grunge aesthetic than what we've normally seen out of other esports. It's gritty, it's rough, and it wasn't meant to be a "high affair/class" style of presentation. Look at their broadcast assets, stage design, soundtrack choices; the VCT has a different feel and I'm glad Riot isn't forcing every one of their esports broadcasts to be completely uniform. It gives a level of freedom for each broadcast members.
Of course, this does differ from region to region (I think East Asian broadcasts still prefer the more formal look than others.)
