Synaptic is able to provide the installed size while listing packages in "installed" status.
I think it would be usefull in muon as well.
I fear this is a bit of a more complicated and general.
What needs to happen is that the view exposes a number of package properties as additional possible columns. Such that you can right click on the view header and select Installed-Size as property.

add columns for Installed-Size, Version, Available-Version
Add more columns to the list of packages and in the "preview changes"
tab. The additional columns are hidden by default and can be shown
through the context menu by right-clicking on the list header.
