Nothing is impossible (;->).

What about a "tracking filter bank"?
Detect the fundamental  (the usual fundamental
detection problems here: zero crossings are
dominated by formants, not the fundamental ...).
Use a set of switched capacitor bp-filters,
and set the center frequencies of these to the
harmonics with a PLL/Divider system.
