we are currently implementing something like this (that is special
customfield with customised editor viewer). Approach, which seems to
work quite fine is adding new type of custom field (which will be used
only in one cf, but it gives us nice separation of code):

% cat local/lib/RT/CustomField_Local.pm 
no warnings qw/redefine/;
package RT::CustomField;

$FieldTypes{ClCustID} = [
    'Select multiple customers',
    'Select one customer'
];

then, we create/add custom field to queue(s). As rt is using custom
field type for selecting which widget/componenet, so it is using:

local/html/Elements/EditCustomFieldClCustID
local/html/Elements/ShowCustomFieldClCustID

they were created based on one of default ones, with added additional
'helper' dropdowns and searches. They use some javascript/async
requests to fetch data from other systems and modify existing controls.
The only thing you have to keep in mind is that the value stored in
customfield is the one which is passed in
'<%$NamePrefix.$CustomField->Id%>-Value' field of form, so you have to
make sure it is filled with correct value.

Hope it helps.
