Will Beastmaster appear in any Endwalker content patches?

You can't do that with the current iteration though without scrapping most of the existing spells. Anything tied to a CC effect on an enemy (which is most of those filler spells), anything with Instant Death potential, anything that significantly hampers you or allies in some way, anything more powerful than what a dedicated tank or healer has access to (ie Diamondback or White Wind).

By the end of it all you'd be left with... what, 3-4 redundant filler spells, Pom Cure, Angel Whisper, Song of Torment and a handful of Primal cooldowns?

Exactly. Limited BLU is interesting because of it's customization, wide array of weird and gimmicky spells and lack of overall balance. To add BLU to the standard heap, you'll have to gut everything that is remotely interesting. Maybe jon, aveyond and Shurrikhan are fine with that because throughout this entire conversation it's all about just getting the job to max level above anything else. I have a feeling they won't like this basic-beach BLU though.
