Yes it will work. I'm running that size tire on a 19x10 square setup myself.

The is the factory size rear tire on the PP1 gt's, the bullitt, and the non HP mach 1's. Also, the PP1 and bullitt use a 9.5 wide wheel factory, don't know the offset.

It will poke out... a lot. Stock PP rear wheel has a +52.5 mm offset so that's over a 1" difference.

What's the recommended offset for this setup, everything else being stock and not modified? Also looking at 275/40/19 tires. Seems to be +40 on Fitment Industries. Thanks in advance!

The ideal offset for 19x9.5 would be +29mm. This spec's outer face position is equal to 10" wide with +35mm offset, which is pretty common flush fitment for the mustangs.
The +25mm offset that was mentioned in the OP, will fit the front without poking but for the rear it will poke about 4mm out, it could be resolved with more negative camber, but you'll wear out your tires(specifically the rears) quite a bit faster.

The lmr pp2 wheels I have are +35 offset as you can see in the Pic below they barely tuck. At +25 they will poke 1 in more than mine.

That's not how it works, offset is based on the mounting surface of the wheel in relation to it's center line so width does not come into play.

This is helpful., thanks! I think in my mind there was a way to close the wheel gap and make the tires flush by just adjusting wheel size. That doesn't seem to be the best route without entering the world of modifying suspension components. I was just trying to avoid re-engineering the car, plus the financial costs involved. I'll look to temper my goals and just aim to make it flush for now.

I understand how it works. But if you care to use some of the online offset calculators you'll see that the width of the rim does affect the fitment. You can compare them yourself. on a 10" wheel with +35 offset will sit further out than a 9" wheel with the offset of +35. And the reason for it, is that the centerline of a 10" wheel to the face of the wheel is 5" and respectively for the 9" wheel is 4.5" distance centerline to the face of the wheel. So in order to get the 9" wheel to sit exactly where 10" wide wheel with an offset of +35 sit, You'll need a +22mm offset on the 9" wide wheel.That's not how it works, offset is based on the mounting surface of the wheel in relation to it's center line so width does not come into play.
Long story short, we are saying the same thing, which is, OP's specs will definitely poke out in the rear. For the front, from my own experience you have 5mm extra offset than the rear to sit flush without rubbing or even using camber plates or bolts.

Width absolutely does factor in when considering where the wheel face and inside edge will end up.That's not how it works, offset is based on the mounting surface of the wheel in relation to it's center line so width does not come into play.
I concur with both of you its about 4mm of poke on the rear, but should be fine for most people on the front.

The outer face of the wheel will stick out further on a wider wheel but the outside of the tire mounted to it (if size is kept exactly the same) will sit in the exact same location was the point I was making. That's what will rub, not the wheel.

Point taken. But… the tread width doesnt change (much) but the tire bead and sidewall are mounted to that wider width wheel so the cross section of the tire at it’s widest point grows with the wider wheel almost 1-1, and often thats what rubs first.

Thanks for all the input guys. The wheels in question were the Konig Countergram as they have the black face/polished lip in a 19" wheel that isn't going to cost $5,000 a set. For whatever reason they only make the chrome color option available in a +35 offset and not the black/polished lip. I spoke with TheMegalodon as he's running the set up on his Triple Yellow and confirmed they will work as he has them with BMR SP763 and about -2 camber all around.
