I’d look at Spy Coast Farm if you want fresh. They have several more compact horses like Cyklon and the lesser known Baldev. If you really want to spring for a fancy one, you could try to get Amaretto D’Arco. But it doesn’t look like your mare has many big name or 1.50 - 1.60m jumpers in her pedigree, so you might not get accepted with “private treaty.”
Personally, I wouldn’t mind breeding your mare to something a little bit bigger or a little bit heavier. I think if the grandparents aren’t huge clunkers, then you’re not likely to get a draft horse. I quite like that Diktator van de Boslandhoeve and I believe he’s thrown some nice babies.
You might also look at Westminster VDL. He’s thrown some big jumpers with great ridability and he’s fairly compact.
