A Hatch pattern needs to be inherently repetitive. If it's even possible [however extraordinarily complicated] to define a pattern involving all the bits making up the letters in those words, then if there's a "word" a certain distance up and to the right of, say, the one at lower left in your example, then there would be another one up and to the right of that by the same distance, etc. Applying it in a boundary like yours would surely result in something like this:

So I don't think a Hatch pattern is what you want.
Is the idea that no matter the size of the boundary, the text pieces would be of the same size and spacing and displacement angle? If the proportions of the boundary are always the same, and if the text size can change to go along with the boundary size, then a Block would work, but I assume that's not your situation. Show some examples of what you're looking for at different boundary sizes. If it's twice as big, do you still want 5 words? Arranged similarly in relation to the boundary (e.g. same distances inboard, but spread out more -- another impossibility with a Hatch pattern)? Etc.
