You have no option now its EASA as of Sept last year. They can't issue JAR licenses any more.
You need to speak to the director of Policy ASAP the long you leave it the less likely you are to get anything but get screwed around to have to meet modular requirements.
Oxford have no input into the license issue I suspect this is some rubbish out of there quality manual which has been signed off by the inspectors so they now deem it as law. The operational requirements rings a warning bell to me its a get out for them if it does take long that 36 months.
I did modular in 13 months from start to finish while holding down a full time job for 8 of those months.
