Consider a middle top link setting.

An adjustable top link will give you the heights you are thinking you need. As I interpret your question....

Here's some pics of my X739 which has a cat 1 limited hitch with a BB2048L box blade, not sure how the BB compares to a RB. The hydraulic top link in pic 1 gets you more lift height but the standard top link seems to have plenty of lift height as well.
