Okay, Jumper is Trilby, that is Trilby compounded with non-royal king move. Trilby is the Trebuchet plus Tripper under recent discussion at Gilman's Symgi and J. Good's Archabbott, where historian Ayer asks of the still rather few examples leaping radially three squares. Jumper is the only explicitly new p-t added to Big Outer. 
As far as that goes, Big Outer really has Rings, three separate ones, unlike other current topic, Gilman's hexagonal Ringworld's name would suggest for itself. What else? In jumping diagonally three spaces, Jumper may leap over one or two squares of the middle ring. Jumper loses the Trilby portion of option within the middle ring, it's just an outer phenomenom. Christine Bagley-Jones citation finds Three-Star General at Operational Chess II as Trilby, that and Operational I being wargames without King, some variantists may not (have) read.
 The ring around a starting square three-removed is particular interest for including the oblique, not radial, end-points in full as the simple Bison, complexified with pathways to Falcon -- become the correct match-up complement of Rook/Knight/Bishop, unlike straight jumper Bison the merely broadened Knight.
Finally, let alone for the moment their cousins Amphibean (which need special definition attempted by Knappen), all of the strict three-square movers Tripper, Threeleaper/Trebuchet, Trilby, Falcon/Bison, Camel, Zebra, Nahbi and so on, can be variegated to still dozens more yet unclaimed differing p-ts by just commonsense Forwards/Sideways considerations, non-displacement capture combinations or restriction, and not least some area effect conveyed by the three Rings of fine cv of Blanchard, Big Outer Chess. And Big Outer has a genuine Trilby thirteen years ago! Actually I think there were either one or two  '(0,3) plus (3,3)' in 1994 'ECV' should anyone take the time to page through it again.
