I'm afraid I don't understand what exactly you mean. A Locator doesn't has to have an appearance at all and you can use of course graphical primitives to display them. What about this here? It uses a small point and shows you the exact location in the graphics:
With[{lines = {Line[#], Line[Transpose[#]]} &@
Table[{x, y}, {y, 0, 1, .1}, {x, 0, 1, .1}]},
Deploy[DynamicModule[{p = {.5, .5}},
Graphics[{lines, PointSize[.015], Red, Dynamic[Point[p]],
Locator[Dynamic[p], None], Dynamic[Text[p, {.5, 1.1}]]}
, Axes -> True
]
]]]
