Figured it out!

0. read: http://www.masonhq.com/?FAQ:Components#h-when_using_multiple_component_roots__is_there_a_way_to_explicitly_call_a_component_in_a_specific_root_

1. perl -MCPAN -e 'install MasonX::Request::ExtendedCompRoot'

2. In RT_SiteConfig.pm:
@MasonParameters = (request_class  => 'MasonX::Request::ExtendedCompRoot', resolver_class => 'MasonX::Resolver::ExtendedCompRoot') unless (@MasonParameters);

3. mkdir /opt/rt3/local/html/Ticket

4. vi /opt/rt3/local/html/Ticket/Create.html with content:
% if ($ARGS{Queue} == 1) {
<& standard=>/Ticket/Create.html, %ARGS &>
% $m->abort;
% }
bite me!

5. mkdir /opt/rt3/local/html/Elements

6. vi /opt/rt3/local/html/Elements/SelectOwner with content:
Pick me! Pick me!

Try to create a ticket in queue with id 1.
Notice how SelectOwner is from local but Create.html is from share?
Try to create a ticket in queue with id > 1. Not happening!

See the MasonX::Request::ExtendedCompRoot for more fun.
