I don't have a problem with the idea, as (same as shops) they can open after lunch. The morning/dawn is the remembrance time, and a game in the afternoon would be fine. But ANZAC doesn't fit in with the season, taking ABs out for two SR rounds would be shit.
A fix would be to give SR a proper season length, and except at certain times there are no internationals. Proper longer season with full home and away as well as knock outs maybe and get the balancing factor of teams that are stacked playing without them - and more opportunities for wider TG players
