Co-grazing Cattle & Pigs

We're planning on switching from upland sheep grazing to a small herd of 5 Dexters which we hope to use alongside our 2 existing Tamworth pigs as proxy ecosystem engineers to drive dynamic ecological change on site to support the regeneration of temperate rainforest, invasive species control & break up the dense swards of Molinia across our farm.  Has anyone else co-grazed heritage breeds of cattle & pigs in this way?  Really keen to learn as much as possible before their arrival to avoid any pitfalls - thanks so much!
