Harmony of Purpose + Radiant Crusade

Harmony of purpose is not really used in any minion builds, despite synergizing quite well with the elemental relic skill.
I think a lot of this has to do with the challenge of landing a link skill on the Sentinel of Radiance in the midst of all the other minions.

Would it be possible to add another skill to Radiant Crusade called "Radiant Link" or something like that?
This link should be limited to only link to the Sentinel of Radiance without any targeting required. This way the link playstyle is also possible when you are not in a party which i really hope for.

I don't think it needs anything else, but if it's too boring or if you want to add it as another notable skill my suggestions are:
a) adding the burning aura to the link (similar to searing bond)
and/or adding some of the older guardian notable skill effect
b) Targets and allies in link beam gain onslaught for 4 seconds
c) Enemies in your Link Beams are are Intimidated/Unnerved

Never used Links because I'm mostly solo and they seem clunky, but this sounds like a good idea.
Do you die if minions expire? Would need a permanent Sentinel then.
