You have never been to UK long enough to understand the UK laws.
CAA would stick to the rules no matter how much money you spend on solicitor or lobby it in your way. Unfortunately, only CAA approved courses and EASA 147 approval organisation course certificates are recognised by CAA.
It is better to convert into Ireland EASA or other EU EASA AMEL ( if accepted) before approaching CAA for conversion. Afterall, other EU EASA AMEL is as good as CAA EASA AMEL in EU.
