You're sure that adelphos could never be used for step-brothers/half-brothers?
And before you start there is also no evidence or reason to say that these were Joseph's children by a previous marriage.
There's no evidence to say they were not either.
Name one person in Scripture who is a child of Mary. Just one.

"Is not this the carpenter's son?," the Jews asked, "is not his mother called Mary? And his brethren, James, and Joses, and Simon, and Judas? And his sisters, are thy not all with us? Whence then hath this man all these things?" (Matt. 13: 55, 56).
Thats 4 and if you count the sisters....but still you will not accept this because it would kill the doctrine of the perpetual virginity of Mary. I understand your problem Dave, you're in a no win situation here.
When you have studied both sides and shaved away (Occam's razor) everything the plain truth screams thru.

While we're at it, do you intend to answer my question regarding the possibility of you having any position concerning the brothers/sisters of Jesus other than the "official" RCC (infallible) teaching?
Jesus. :-)
