My question is, if one were able to source these plugs, 3-d printed or otherwise), would they work in the Valencia's 806A horns as well?

Forgive me if this is a stupid Q, still learning about these classics.

Thanks all -

There are two schools of thought on Tangerine phase plugs. I peronally like the old ones better. I'm open to the idea the Tangerines might be slightly better, but not convinced. They certainly aren't dramatically better.
Best improvement for the 846 is the crossover. Newer Altecs had a mid level control, which is a dramatic improvement. You can't increase highs with a passive crossover, but you can reduce the mid, so there are effectively more highs.

The HF circuit from the 30904 might help.
