First of all JAR OPS 1 is only applicable if you are flying under an AOC, Werksverkehr is not covered by that. Second, you can get excemptions from the factoring required by JAR OPS 1, but you have to apply on a case by case basis to the LBA. We did it for our premier into Albenga and got an approval, however for private flights (of the owner) only.
Best of all just ask the LBA and give them all the relevant information, they are cooperative if you are as well.
