One thing I found that really helps free your mind from "the tyranny of pattern practice" and gets you thinking about how to construct rhythmically interesting musical phrases is to decorrelate the length of the scale snippet from the rhythmic subdivision.
So instead of matching up the four scale tone fragment with a four 16th-note phrase and/or matching up the three scale tone fragment with a three triplet-note phrase, mix & match: Try walking up the scale in three scale tone patterns with a four 16th-note phrase [Root-two-three-two, three-four-three-four, five-four-five-six, five-six-seven-six etc] Then try walking up the scale in four scale tone patterns with a three triplet-note phrase [Root-two-three, four-two-three, four-five-three, four-five-six etc.] Then try walking up the scale in three scale tone patterns with a five quintuplet-note phrase [Root-two-three-two-three, four-three-four-five-four, five-six-five-six-seven etc.] or try walking up the scale in five scale tone patterns with a four 16th-note phrase [Root-two-three-four, five-two-three-four, five-six-three-four, five-six-seven-four etc.]
Then try doing all that with arppeggios! It's a brain-buster, but I found it really freed me from some of the traps of too much rote muscle-memory practice techniques.
