Are there any technical issues that prevented you from implementing it?

Nope, nothing fundamental. The only reason we didn't have interleaving in the OFDM Reference Design was that it seemed too hard to build at the time. We've since built interleaving as part of the 802.11 Reference Design, where the Tx and Rx PHY System Generator models implement the interleaver/de-interleavers specified in IEEE 802.11-2012 18.3.5.7. You could use these as a reference for building your interleaver in the OFDM Ref Design PHY.
