I don't believe that the $Organization value is displayed anywhere in RT's interface. The value affecting the top-right corner is $rtname. This can be changed without breaking all existing ticket links.
Making a localised modification to the page template element responsible for that top-right corner is another alternative. Different subject tags per queue are managed within RT's admin interface (Admin > Queues), not RT_SiteConfig.pm. These take plain text, not regexes, as they specify what should be going out. The only remaining concern is what should happen if someone sends mail to RT with old subject tags. Given an email with a subject containing "[XXX #1234]", RT will only associate that email with ticket #1234 if it knows that XXX belongs to that particular RT instance. If not, RT will ignore the ticket number and generate a new ticket instead. That's where $EmailSubjectTagRegex comes in. If you're not worried about old emails being replied to and generating new tickets, no further action is required. Otherwise, construct a regex that matches all old and new possibilities for XXX above, assign it to $EmailSubjectTagRegex in RT_SiteConfig.pm and then restart RT.
