Nothing will help the 25 cal. Low BC bullet problem. The 280AI is a great round , as you know.Use at ballistic program to compare the 25-06AI and the 6.5x284 out to 1000yards and you wil understand why I say forget the 25-06AI and go with the 6.5x284!
You are correct on most counts.
However, it's worth noting that....
25-06 will push an 80gr TTSX about 3800 fps which is great for varmint control out to 400-500 yds.
260 Rem will almost keep pace with 6.5x284 at 1k. But, at 600-800 yds it may have an edge for spotting and follow up shots. ...especially if you drop down to 130 gr bullets when wind or distance isn't too bad.
