I almost hate to bring it up, but it is a fact that both ancient Hebrew and Greek were written in what we call all capital letters. When King James (and most all other English versions) capitalize "holy" and "spirit" sometimes and sometimes not. The problem is that when we see it capitalized we immediately think it is talking about a person. In any case, it prevents us from understanding it the same way those to whom God originally wrote understand it. It's a deep subject that require a certain amount of scholarship, so, knowing you don't like scholarship, I won't get into it. Still, without that understanding, the book will remain largely unintelligible in the area of holy spirit.
You are correct that the capitalization is part of the translation, not the text.
The uncials don't really affect places where the Holy Spirit is written of as a person. You can go with uncials or miniscules, but the passages read the same. You can make the argument that "holy spirit" refers to the quality of spirit God annoints you with, or however you want to think of this,but that's not at all there is to this discussion.

The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:
The Holy Spirit . . .
Made you overseers.
Said "separate me Barnabas and Saul to the work whereunto I have called them.
Can be lied to, and that lie is to God.
Can be grieved, that is, made very sad.
Speaks.
Teaches.
Reminds.
Has Opinions.
Forbids.
Witnesses.
Prophesies.
Sanctifies.
Signifies.
And all this signifies to me . . . the Holy Spirit is a Person within the Godhead, regardless of capitalization.
Much love!
