Having to make a choice

I have to make a decision, and I need help. See, I started working on a Ret-con origin for Commander Steel, and I came up with a unique way of dealing with the cyborg aspects of his story - without making tech that would be difficult to explain. But Lilith said it didn't really work for that universe. So the question is, do I drop that aspect, and try something else, or should i make the story not a part of that universe and keep the idea, cause its interesting? What do you guys think?
