as a old sound dude i used to keep a DOD Fx10 bifet preamp in my mic kit to accomodate the "guest" acoustic player the tone control on it would help solve the usual "mid" howl to get a usable level and buffer the weak output of the piezo's.
shame they're hard to find now...
one of those ahead of a distortion might just do the trick.

I have seen one in person, but of course wasn't allowed to dissect it to see what was inside. I later learned it apparently has three piezo ceramic discs. It's in a rubber innertube-like wrap with I think velcro. It typically goes around the lower bout at the 'points' or 'corners'. It's said to not need a preamp but if you are trying the low end of a bass with piezos (I don't know freq. range of a cello), a preamp with hi-z (higher than 1 M guitar amp, like 5-10-20 Mohm) input will serve you much better.
On my bowed instrument (violin) the band picks up even more feedback than my Fishman (piezo bridge pickup).

I find it useful to use a dynamic expander first in the signal chain. It both acts somewhat as a noise gate and allows more touch-sensitivity at higher gain, which I find bowed instruments particularly lacking in, especially since the bow noise to signal ratio is ordinarily pretty bad when playing softly.

It is probably possible to feed an EQed signal into the peak follower of the dynamic expander, but not to the signal input, so that only frequencies that don't tend to cause feedback are considered as a reason to amplify the signal. I haven't experimented much with this yet, but I can already play loud enough to annoy the neighbors.

Have you heard "The Sanctuary" by Darling Violetta? It was the theme song for the TV show "Angel" some years ago.

I'm not sure how much distortion is on the 'cello, but I love the way the cello and distorted guitar sound together in this song.

I think you're going along a good route here. I play violin/fiddle and have had ongoing pickup saga's for years. Magnetic is a good route I reckon.

I have also used a band and A: There not feedback immune, B: Do require a HiZ input and C: Lose a lot of top end, presumably due to the rubbery interface.

An sm57 is also not a solution.

Why not try attaching some magnets to the end of the fingerboard, with pole towards string.
At your nut electrically connect C string to G, D string to A.
At tailpiece connect G to D. Connect C and A to the primary of an 1:20 transformer.
Jack plug on secondary of trafo and plug into a nice chunky valve amp...
