In the first concept stage, tczs made from fetched debs was the package format for dCore, but at the time it was difficult to work with the circular deps in Debian as well as being slower overall with loading. Slower because Debian's packages are much more factored out than Tinycore's. Gcc is broken into 20 packages in Debian, but only 4 in the standard TC repo. I am sure I could get the imported tcz format to work now that I have spent over 2 years with dCore, but it would in a way mean starting over from scratch with importing, updates, etc.
If you are talking about the option of also using the standard tcz repo, then no, there is not library compatibility so it would not work.
