Contractor receiving two awards under the same IDIQ?

Is there any regulation, legal precedent, or OCI issue that would preclude a contractor from receiving two awards under the same IDIQ contract and then subsequently competing for task orders under the IDIQ?

Background: The Gov't issues an IDIQ that consists of two pools: Small Business and Unrestricted. The RFP states that some task order competitions will be set aside for the SB pool, and others will be Unrestricted, and that the Gov't anticipates a total of 10 contracts will be awarded (5 SB and 5 Unrestricted). The RFP goes on to state that for the Unrestricted task order competitions, the SB IDIQ contract holders may compete against the Unrestricted IDIQ contract holders. 

Let's say there's a LB contractor who submits a proposal for the Unrestricted pool, and then also submits for the SB pool under a SB Mentor-Protege arrangement. Also, let's say the Protege under this Mentor-Protege arrangement will be a named team member/subcontractor under the LB contractor's Unrestricted contract.

Is there any issue here with regard to OCIs, limiting competition, collusion, etc?  If the LB had a good reason to want to submit a proposal from both the Mentor-protege entity and the LB entity for an Unrestricted task order competition, is there anything that would preclude it from doing so?

Thanks in advance.
