john might've been the walrus, but paul was a cat
Considering there is no house, no studio, no cast, it won't be in Q1 (up against MAFS).
Q2 is olympics territory so won't go there, but Olympics will rate well so provides a good platform for promotion
Most likely ends up in Q3, although if Ch7 are worried about clashing with AFL may end up Q4.
edit: I see it as most likely running (assuming 90 days/3 months):
1. August - October
2. October - December
3. April-June
April is typically the tail end of MKR season, and House Rules typically slots into that April-June gap. I would guess it's gonna be August, up against the non-All Stars Survivor. 7 don't screen Sunday AFL games and the Friday broadcast doesn't start till 7:30 usually anyway so it's not like Big Brother would interrupt their current broadcast schedule there.
