If doing 1-3 day trips, I'd be much more inclined to run with the tarp. Which bearpaw one are you using?
The whole woobie thing looks awkward to me, but I guess people use it. I like a decent insulated (primaloft for me) jacket and pants that can be thrown on over top of stuff for glassing and zipped off for moving. Seems like your down jacket will fill that role for you. I'd ditch the impertech for sheep, but that depends on how much rain you are likely to deal with.
As an exercise, I like to cut my gear down to the minimum I need to survive, then add luxuries from there. First luxuries are in sleeping well/warm.
For 1-3 days, I'd probably have no "spare" clothes, and your food weight can be cut way down. Good way to go. Have fun with the hunt prep.
