You asked about MR popup 38. I'm using a MR popup 18 for this, which I really like. I put saddle platform in the load shelf, my 2-step sticks sideways in the load shelf (I HATE sticks sticking above my head as they snag on every branch I duck under), and if i need a heavier pair of bibs or something for cold wx I roll them up and strap to the top of the pack bag. I have packed out an entire quartered antelope in this pack (quarters bone-in) along with rifle hunting gear, but where I hunt whitetails we're required to weigh in the entire deer so not allowed to quarter in the field, so I havent done this with saddle gear on board. The pack itself is more than capable of carrying a deer, but to do so with stand and sticks you'd end up having to strap stand and sticks and anything else on the outside. If you had a 28 or 38l size I think you'd have more room for heavier clothes, could put saddle platform in the bag, etc, so I'm sure it would be tight but I do not think you'd really have a problem with either. I've been doing more late season hunting and have been trying to decide if I need a lighter, more packable pair of insulated pants, or a 28l version of this pack. Havent decided yet.
