Current mirror with Darlington pair + Joule thief

I am trying to build a high current driver for an led array.
Can a Joule Thief with a current source mirror that is using a darlington pair on the load side be all combined?

Can electronic splice programs simulate the result?
Any hot areas to worry about with increase in amp?

I want to build an efficient constant current source driver to deliver power to an array of SST-90 LEDs.
source:14.4v battery (automotive battery)
current @ 5A or 9A to get enough lumens
(have considered buck/boost circuit)

Thanks ahead.
