Is it possible to install multiple APIs of LBaaS per tenant?

Issue

• We are evaluating the possibility of providing LBaaS on Red Hat's Openstack platform not with the native API but with a provider API (Radware Alteon vDirect). We have the question of whether to install this propiertary LBaaS limits us and we can not use another solutions (other propiertary or native of Openstack plantform) of LBaaS simultaneously.
• If we have installed the radware's API LBaaS, is it possible to install other API of LBaaS and choose which one we want to use per tenant?
