While it looks good in a simulator I can pretty much guarantee it will emit smoke if you built it 😀, class AB amplifiers are very susceptible to thermal runaway as one heats faster the the other, the result is it shorts out the power supply, in general it's best to use it in the feedback loop of an op-Amp or discrete differential amplifier.

Maybe you can use a vbe multiplier circuit and local negative feedback.
