I agree with Duo Armadyl's post, a new jad cape (could) be great, as long as it doesn't undermine the already existing best cape in the cape for some purposes (Ardy cape 4).
Players (including myself) have invested a lot of time and resources into acquiring that cape mainly to have as best-in-slot for doing team corp. All that time and energy will have been for nothing if a new, better cape is introduced with far less requirements. Anyone would be able to get it, even if they had to get a friend who was better at fight caves than themselves.
Perhaps, create the new cape as you've advertised, but reduce it's effect at corp to make doing the Ardy Elite diaries still worth it? As that's why most people who aren't going for the achievement diary cape get the Ardy Cape 4 in the first place (corp).
