I think a mix of DIS S1 Klingons, DIS S2 Klingons, TOS/ENT S4 Klingons, ENT S1-2 Klingons, TMP Klingons, & Kelvin Klingons (masked uniforms) makes sense to see. Its an empire - its citizens are going to be very diverse in appearance. It’s the same reason its not problematic that there are ridged Romulans and smooth forehead Romulans of various skintones.
There should even be Klingons who wear pink armour unironically, like in TAS. Klingon blood is confirmed to be pink after all.
