Looks good and hopefully it can host some AFLW (and continue with VFL) games with a better suited (ie higher) capacity.
On the note of a boutique stadium, now that ardern st is on the metro tunnel, put some money into that being a replica of GWS stadium, seating 30k to 35k. If that can't work, then do it at Western Oval. Then each Melbourne stadium (MCG, Docklands, Boutique) can host games depending on expected crowd turn out to maximise revenue/profit for the clubs. I know the MCG is the spiritual home for a few clubs, but I'm not sure there's much sense in playing Melbourne v GWS at the MCG, unless the club is happy to cop the loss. I would also aim to bring back the 2pm match where possible to avoid overlaps in other slots which a 3rd Melbourne stadium would help with (every game is stand alone except for the 3 or so played at 2pm Saturday to maximise eyeballs).
edit:
Western Oval using Metricon Design:

Would need to buy the dealership, and incorporate the childcare into the stadium (easily done), fits quite easily otherwise.
Melbourne home games at Footscray
There'd genuinely be 100 people there.
