I dunno about those, I think Takara arent the greatest of models to use. and anyways the bodys wont fit most likely. If you want a custom tank all you have to do is make the main body of it, then just steal parts off a high quality model like roco. What model do you want to build. I could maybe help you out with finding a suitable model and giving you some basic instructions on how.
