What you COULD try is to use a 2nd pole on each side angled back towards the Bongo. Provided the original poles could not pull out of tbe ground and that the tops of the two poles, where they meet, are bound/linked together, and the angled poles don't slip on the ground, the triangulated structure should work similar to using guy ropes, but using a compression strut instead of a tensioned guy rope. But it would all be bulkier, time consuming to construct, and you could still trip over the angled pole
Taking a lateral look at the problem, i'd use storm strap webbing and beefy pegs as the solution, thus greatly increasing secure fastening in wind (and believe me, you need it) whilst making guy ropes as visible as poles. At night, i might drape led string lights down the storm straps for extra visibility.
