YOU might request vectors to intercept and track the localizer but make it CLEAR YOU ARE NOT INSTRUMENT RATED.
You should co-ordinate with an EDI ATCO prior to departure and avoid speculation on here. There's at least two foreign based pilots giving you information on here - they mean well, but just contact the SATCO and don't listen to the rest! I have a friend in the tower there now. I'll see if I can persuade him onto this thread.
Before you go asking for radar vectors for an ILS (practice or not), you should find out what the navigation charges are. The last time I went in to Edinburghwas over 15 years ago in a Cessna 310. They charged me over 250 GBP back then for landing and one nights parking. A month later I received a bill for navigation charges in addition to the above! Self positioning onto the ILS (if permissible) may be cheaper.
