TCA Party of an Existing Customer be Used as the TCA Party for a Supplier?

Can the TCA Party of an Existing Customer be Used as the TCA Party for a Supplier? 

The ability to query an existing TCA party and create them as a supplier is not yet available .If the TCA party is a SUPPLIER party , then we can query that party and create a CUSTOMER ACCOUNT  for that party.
But on the other hand ,if  TCA party is CUSTOMER party and we query the customer party and want to create a supplier Party then two parties will be created , reason is that unlike CUSTOMERS, most of the options and details that define a supplier are not stored in TCA tables, but in separate tables AP_SUPPLIERS and AP_SUPPLIER_SITES. In order to enter these details the Supplier form or Supplier Open Interface must be used.
