It needs to be explained why/what are the requirements that you need both (IPVPN and EVPN) in the same solution because this is not a trivial complication. The complexity of the solution depends on the requirements. If majority of traffic in a (significant class of) data center is inter-subnet, a solution should be optimized for such traffic and, hence, solving the forwarding of such traffic should be the starting point.
