Right now, this is not possible using any built-in mechanisms.
(See the per plugin interval feature mentioned in another thread though,
which is available as an RFC on Github.)

However, you could simple skip a couple of intervals in the read
callback function. I.e., use a global variable (for each instance of the
callback) to count down the number of intervals to be skipped. Make sure
to return 0 in case you skip the current interval. Then, manually set
the interval appropriately when dispatching values.
