@tofer = not stupid questions. Yes this can be done. Establish communication with the artist (preferably both e-mail and voice, and hopefully you share a common language) and make sure you ask all those questions above and that she is onboard with the scope, ideas, duration of visits, etc.
It is preferable not to tattoo over the same areas prior to healing, but tattooing near freshly tattooed areas is perfectly fine, if you're up to the stress. Your artist's planning is, of course, important in the success of this direction.
You already said it - talk to your artist! Also, she may travel to various conventions so that can be an option for you, too. @Tofer It's all about communication and setting expectations. Good luck!
