NO WAY in Italy.
In Italy is not permitted to do laser, so if you did laser and have 0,05 astigmatism and 0,05 myopia, you will be out anyway. Due that i went in UK. ITALY does not apply JAR FCL-3 even if is a JAA nation.
UK apply strictly the limits for initial!!!!
If you are outside limits I suggest:
1 - Ask to AME: if they said you can do it even outside limits and you will be alright if the visit will be ok....you are ready to fly!!
2 - If they said " NO, even with laser you will not be able to gain 1 class"...well, I suggest to go in USA, get 1 class (you will get it in USA, don't worry) and do CPL FAA. Then come back in UK and go to gatwick: they, on the basis of CPL/1 class ICAO (FAA), will apply to you the renewal limit (no limits for astigmatism and -8 for myopia) even if is a initial.
3 - Don't tell them nothing! And Hopefully does not happen anything in the future.
