Default For engine builders, bump compression?

Would it be possible/affordable to bump our 4th gen Hemi's from 9.4:1 up to 10.4:1? Reason I ask is my last car had a 2.5L 4 cyl. VVT engine built from the factory with 10.4:1 compression. It ran 87 octane fine, in fact it was factory recomended! It ran just like our 4th gen hemis do as far as where the power was and how they pull like crazy after 3500rpms or so...It was the first thing I noticed when I test drove my new Ram, how the engines performed almost identically! Except for 1/2 the h.p of course. Just a thought I have had for a while, I was wondering if the block or heads could be decked a bit for a little more compression?
