Haha yeah it is pretty annoying to make the staggered claptons and remove one of the wraps. "Framing" anything inside of two wires, whether they're claptons or twisted wires isn't really easy.
For practice on the framing the core wires inside I would suggest working with twisted 26 or 28g on the outsides, and seeing what you could fit inside properly. Instead of claptons on the outside, try one clockwise twisted and on the other side, counter clockwise twisted wires. It'll make a zipper pattern and will line up.

Here's a concept wire I did a while back before the whole staple staggered fused became popular, it has a clockwise Clapton on one side and a piece of counter clockwise twisted 26 on the other. It had a 20g core, but i removed it and pressed in the Clapton over it in the middle to prevent movement.
