Re: ai vs oi
From your descriription, it sounds like more than a lilt to me. Your 'oi' pronunciation if the vowel in 'high' is the natural pronunciation in your variety of English. If you just attempt to change one or two vowel/diphthong sounds, you will sound very unnatural, both to brummies and to speakers of RP.

There is also the risk of alienating friends, who may feel that you are putting on airs.
