Technics SU-V series AN7062N input amplifier

I'd say that's a no. Not easily, anyway.

By the looks of it, AN7062 is a bootstrapped cascode LTP with a follower output for a single-ended PNP VAS. Your folded cascode job could be adapted for a single-ended NPN VAS but compensation would have to be taken care of. For a PNP VAS you'd have to do a complete polarity flip (with pnp <-> npn).

Also note a drafting mistake - I'd think T5 emitter and T6 base should be connected.
