I actually got John East, ( he's a really nice guy), to put two set of East ACG filters in my standard Europa bass a few years ago because they had the CVQ and I thought they would give me a poor man's Series II sound. I had low and high pass filters on each pickup. What I liked was the filter range was down to about 45hz so I could get a really good dub sound but I found the low mids were weak and so the bass didn't have the low down punch to drive the sound that I was used to especially when playing reggae.
I've now restored my bass back to original alembic spec and put the filters a non alembic bolt on bass and it sounds fine in there. Still not punchy but then it's not a gigging bass.
If I was looking for a persuader I wouldn't be put off by the non alembic innards, I'd try to get a discount and put the saving towards some original electronics from Mica.
