The impedance differences could be addressed by swapping out voice coils in the HF units to match those of the woofs, or by bi-amping into an electronic (active) crossover.
Series or parallel resistors of the appropriate value coukld be placed around/in-line with the 16-ohm units so the amp "sees" equal nominal impedances on each driver if still using a passive network.
Others may jump in here to correct me or offer more specifics, but I have a good sounding setup of A-5's with 515-8G's, 288-8L's, and 1005B horns, through N-1285 networks. Sounded really nice this Wednesday afternoon past at my clinic's summer BBQ at my place. Low volumes but effortlessly portrayed outdoor musical imagery from 200 feet away.

Thank you for the warm welcome and thanks for the tips. Just some q's sir, . I wanted to keep the drivers as original as possible, (Im a nostalgia freak and love vintage audio) would swapping the voice coils in the HF driver change the original t/s parameters? The active crossover looks like a better alternative for me but am open to options.
The series and parallel transistors also seem to be less intrusive.

Do you have a photo of your current A5 setup? Would love to see it.

Btw, I've read that these drivers can be powered by flea powered tube amps, do you think its possible to run them via triapath t-amps?

Thanks,
Earl
