There's now a tool to make Dizzy (or like) games for 128K Spectrums

Only issue with it is that your finished game compiles to a TRD file. Anybody know how to easily convert a TRD to TAP/TZX?

It may be doable but it would mean rewriting the loader, and replacing the TR-DOS CALLs with appropriate cassette loading ones. I'm also not sure whether anything gets loaded during gameplay or if it's all done before the game starts.
