So far the biggest array I've found with suitable arrangement is the CA3081 - 7 NPNs with common-emitter, so I can divide the input emitter current by 7. The output will be reflected in a PNP mirror, made from an MPQ3906.
Unfortunately, MPQ3906 transistors are not matched.

Have you looked at the BCV62?
