Can we get upgrades of these old sentinels? And bring back collar prime on future relics or a varzia exclusive relic for normal aya?

[Redrigoth]

Can we get these along with future prime releases? Any plans to ever release such things?:

• Diriga wraith
• Djinn prime? Was it tenno before it got infested?
• Oxylus Vandal
• Taxon prime?

Also we get a way to farm Kavasa Prime Kubrow Collar such as from varzia relics we can buy for 1 aya each? Maybe improve the buffs the collar provides if it makes sense too.
