A couple comments that I might make specifically about the stock:
The Oracle came with a carbine tube, buffer, spring, and stock. The Magpul PRS will be $200-250 just for the stock, but you'll have to change out your buffer tube, buffer, and spring too, $50 at least on top of the stock cost.
The PRS stock on a 16" Oracle upper is going to make that thing balance like schitt. Maybe I'm more particular about it than others might be, but I've put my PRS stocked lower on a carbine upper before, and it balances completely wrong for me.
Now, beyond that...
I personally like a lot of scope for mid to long range shooting, so a 4-16x44 would be in my wheelhouse. But it IS a lot of scope for short range shooting, especially if a dog comes in hot and heavy, or you catch him in your backdoor. Since budget doesn't seem to be a limiting factor for you, you may consider adding a scope rider or a 45degree offset rail with a red dot sight.
The Geiselle triggers are second to none, but I'm always very hard pressed to recommend one for any factory barreled rifle. For half the price, you can buy a Bushmaster Match 2 stage or a Rock River Match 2 stage or Varmint Match 2 stage, and have a trigger 80% as good (with a Mil-spec standard trigger on your Oracle being 5-10% as good as the Geiselle).
You're definitely going to have an upper that does not match your lower after these changes. Your upper is a fast handling, short to mid-range rifle. The lower with a Geiselle and PRS is a long range/bench rifle. Something to consider.
One disadvantage to the PRS is that the advantage of adjustability really doesn't matter after the first day you own it. Once you set it, you'll never turn those knobs again. If you were passing it around among a lot of shooters and letting them set the stock up perfectly for themselves, sure, it's a great stock, but a guy can adjust the LOP and cheek height of an A2 with permanent solutions for about 1/3 the cost of the PRS. Something to consider also.
