OFDMA is a higher-level concept. Since it doesn't really apply to IEEE802.11, no, gr-ieee802-11 isn't the best place to add it to.
Use GNU Radio's built-in OFDM framework. It's very flexible. From a transmitter's point of view, OFDM is a MAC layer choice that only affects the subcarriers used in every symbol, and you can perfectly well define that with said framework.
