Jar23 A/c
Beside this, which is actually not better to express, neither a A320 nor a DHC8 are JAR23 Aircraft. I personally have no experience of converting a ICAO to a JAR Lic. but if the requirements are like mentioned in your post you`ll have to review it!
If so, maybe the C525 could lift you up, but either not reliable!
