Hi @MichaelAnd1 ...
I completely agree with @Hildi_Pardo. This would be good for you to submit as a new idea here in the Community.
I'm not sure if your school has purchased the DesignPLUS product from Cidi Labs, but in that product, there is an option that Canvas administrators can enable that makes student profile pictures larger in size...just what you are asking. I don't have an example of what this looks like, but it does make profile pictures look larger (large squares) on the "People" page, and it is much easier to see the profile pictures students have uploaded to their Canvas accounts. DesignPLUS has a lot more functionality, but I wanted to point out this particular option within the toolset ... so you are aware of this capability. Hope this helps in some way.
