Tier Rewards past Gold?

Right now, there's no difference between rewards of Gold/Plat/Dia/Master other than border. What if they gave customized recalls for all ranks above gold?

At plat tint it a light green (maybe an insignia under-foot) Diamond getting a dark and sparkly/shiny blue recall with some fancy insignia Masters getting a shiny silver-colored recall with an insignia Challenger getting a shiny gold-colored recall with an insignia

H1Z1 did something similar, each tier got a fancier and fancier Emote while holding a crown of their rank
