To expand the eggs and cheese which are my only CM protein options, I was thinking if I see enough progress to try out having half a Haas avocado, which I gather from Atkins is low in NET carbs...

Has anyone else tried this, while still doing primarily CAD/CALP or eating one main meal a day/IF (intermittant fasting), and making a <8g carb snack + coffee with cream your only other intake?

Possibly not, but "if you don't ask you won't get"!

Edit to add I KNOW avocadoes aren't a high-protein food but they are quite fatty and I love 'em... and my night-time CM is a snack, not a meal.
