Multis and triconodonts (those few that are well enough known, that is...)
sprawled likewise, and are commonly thought to be closer to Theria than to
Monotremata. *Morganucodon* is also reconstructed as sprawling. So I think
you're right. But I don't know how much mobility, maybe enough for a
semi-erect stance, was possible in these animals.
