OSM? So you wan't to use it in JOSM? Then I would start with WMS, to make it a bit easier.

  vbmp_grid:
    srs: 'SR-ORG:6639'
    tile_size: [512, 512]
    res: [1058.33545000423, 423.334180001693, 211.667090000847, 105.833545000423, 52.9167725002117, 26.4583862501058, 12.7000254000508, 6.3500127000254, 3.1750063500127, 2.11667090000847, 1.27000254000508, 0.63500127000254, 0.31750063500127]
    # since origin is nw, only min_x/max_y are critical,
    # just ensure other corner is south-east of Virginia
    bbox: [-37232800, -477758.7842, 697942.5282, 45581000]

MapProxy calculates the grid always from sw, so you need to pass the complete BBOX here.
