Larry: The Code requires parallel breakers to be designed for this application (internally ganged). Just using a handle tie does not allow you to use the poles in parallel.

So in theory the 2 60 amp breakers "Could" work but. My concern would be that they may not be tripped at the same time where they are not internally ganged. I can't say "Go Ahead" but.

The customer has a Midnite DIN box and wants me to use it for the controller output. I am out of 150VDC breakers but I have two 60 amp breakers. Is it safe and reliable to use the 2 breakers in parallel for this purpose? I can pin the two handles together. There will be other circuit protection at the battery.
