Setting relationship between AR Customer type 'Person' upplier as type 'Supplier' in R12

I would like to know if in R12  we can setup relation between our Customers in AR and our supplier in AP?

Currently, we are in release 11i (11.5.10.2) our customers are set up with a type of Person or type of Organization.ing

we are in a process of upgrading to R12 this November.

In our AP our supplier set up as a Employee or Supplier.

My question is as follow:

   1- In R12 how can I setup relationship between our AR customer that have type of "person"

       with our supplier with type of "supplier"?

   2- I know we are able to setup relationship between AR customer with type of "organization"  and our supplier with type of 'supplier' However, most of our AR Customers are set as Person type and not organization. Therefore, we can not make this relationship. Basically, we have our members setup in AR  with type ofPerson . Also, we have setup the same members in our AP supplier as Supplier type. Now we would like in R12 identify these members/suppliers and relate them via TCA relationship.
