If a foreigner came to my country and asked me to speak to them with an accent from another country, I would be insulted.

If living in a region or a country I like to learn the local dialect.

Although I admit that leads to general laughter later e.g. when I spoke Spanish in Seville people laughed at my hick Cuban accent, and then in Madrid they laughed at my hick Andalusian accent!

However I think trying to learn accents helps you a lot later with your spoken language ability... I have seen how strongly some regional people negatively react to a "correct" Spanish Madrileño accent (seen as very snobby/uptight/unfriendly). I had fun the other day taking to a Chilean: I could hear some parts of the accent which were reminiscent of Sevilla, so I could mimic some of the Chilean accent and not sound like a twat (and we had an awesome discussion about it too).
