I have a CASA licence and an EASA B1 converted it from BCAR section L. Of course with change there are winners and losers, some of the older guys have struggled with the electrical conversion and were left with restrictions on the licenses.For me having all the type ratings on the licence was a bonus as it consolidates everything into one document.This will not be such a gee wizz for you as you already have the type ratings available.Watch out though,this conversion process and addition of subsequent approvals has been a large source of revenue for the C.A.A, most employers pick up the Tab but the contrators are left to foot the bill. When all is said and done if the LAME,s get to work in Europe with less conversion (Air leg perhaps) then a lot will be happy with that,
Good luck let me know how it progresses,
