I wouldn't try the 1458's - you might as well be using LM741s!
I have some LT1002ACN's around here - they may prove interesting. I already have that circuit in a sim - but it would be good if we can match caps/resistances as closely as possible.
TL072's might be interesting as well, I have a dozen or so of them.
