Depending on the design, I think Olympic Plaza still has a ton of space to work with. The current plaza design is very choppy, section are broken up and walled off (highlighted in yellow).
The Stephen Avenue portion is hardly considered part of the plaza at all in the current design, which doesn't have to be this case. More meaningfully incorporating Stephen Avenue and designing to remove a few visual/physical barriers could leave more room for stuff/events than the current design, even with a big new building.
Now if really want to get serious, merge the municipal plaza with Olympic Plaza and design MacLeod Trail to be closed for major events. That would nearly triple the amount of public space evaluate.
