Annetta, given your requirements, I would look into Sandro Hit or a Sandro Hit son.
Mo Swanson has had very good luck with her Rotspon mare Rhussia crossed with Sandro Hit (licensed AHS stallion Somer Hit who is also been very high in the National Championships as a 4 and 5 year old http://www.horsetalk.co.nz/news/2011/06/137.shtml) and crossed with SH sons.

You could possibly preserve some of the jump too.
