Looks good on paper.
As far as I know the delay lines can be clocked over a pretty wide
range. At the low end you'll have the clock frequency in the audio as
the limitation, and at the high end the bucket brigade will probably
start to fall apart (the "water" will "splash out" of the "buckets").
Also keep in mind that there will be some wild glitchy stuff loaded up
in the delay line left over from the sawtooth reset, which may sneak
into the output. There should be a way to do some math and figure out
how the length of the delay line will affect pitch shift range -
probably a fun excercise.....
No matter what I think it would produce something interesting to listen

I came up with a fledgling idea for an analog pitch shifter, using
bucket-brigade delays. Feel free to shoot it down if necessary - all
