Table of IPA spellings of english words in different accents/dialects.

I have a list of IPA spellings for about 120,000 english words, in a general American english accent.

I was wondering if anyone knows of an equivalent list for the RP accent, or an Australian accent?

Alternatively, I doubt it's possible, but a set of rules for translation of IPA spellings from one dialect to the other would also be very helpful.

Thanks!
