Is is safe to do a DynaQuad connection between the positive terminals of mini Class D amplifiers ?

fwiw a chatbot suggested "yes". I'd like to try it with TPA3116 - TDA7498 - TPA 3118 - (Kinter has a 4 channel 3118 amplifier with only stereo input - two of its channels could power the extra speaker(s) IF safe.

Whats the story?
