I think that many great ideas are already presents into the Telerik Asp.net Web Suite and that many of them MUST be "imported" (as soon as possible) into Kendo UI. Controls like SocialShare, File Exporer, Image Editor, Lightbox etc are some "must have" that will be fantastic to see into Kendo UI. Or for example having many of the Telerik Ajax Editor features into Kendo UI editors can be take into account.  I suppose that trying to unify the "Telerik Web Controls World" can help future implementation (sharing things like XAML and Silverlight also if more difficult but maybe its easy for client side) and developer technology adoption or mixing. I suppose that "importing" some of these features and controls is faster than start from scratch. I know that is a generic suggestion and i cant hope to see a completed comment for this (but it will be excellent also for partial results) but as Microsoft is moving into One Asp.Net it will be a great things see Telerik going to a One Web Telerik Suite talking at an high level abstraction. If a web control is usefull in asp.net it will be also for kendo ui its only implemented in a different way.
