then don't do it. I don't care about the Golden Knights and the concern of proximity with name, just adds an element to the rivalry. If you HAVE to, drop the Golden and use Eagles but use the golden eagle not a bald eagle. The Grizzlies name would need to be bought from the ECHL team but they could rebrand to Golden Eagles or whatever.
Nothing I have heard (and I could be ok with Blizzard, Raptors, and a few others) top the names with established history. Golden Eagles or Grizzlies are just better. May be on the bit "plain" side but they are regional, have history, easy to merch, and pretty agreeable to most.
So many options including Swarm, Venom, Stingers sound like U12 soccer names.
By the way, MLB will get here; maybe years but it will get here; and the Bees should have a corner on the "bee market".
