Alas, I have not done what I think you want (which is to say, to use the extented CCP4/MRC map header information to represent an arbitrary rotation/translation).
After having read Tom's reply about these rotation/translation/interpolation issues on the ChimeraX mailing list I'd like to correct a misunderstanding I had about what Coot wasn't doing. There is an unused (by Coot) slot in the CCP4/MRC map header, I had thought that the slot allows rotation and translation but it does not - it allows a shift of origin (translation) only. Everything Tom said was on the money.
