LTC7151S Dual Design

I need a fair amount of current for an FPGA design, 22A by my estimate. Is the attached two-phase dual LTC7151S circuit acceptable? Any suggestions/critiques welcome.

I will also be using a similar design to generate 4V for RF circuits that will then use LDOs (LT3045) to sub-regulate for a 1/f phase noise-sensitive application. Suggestions/critiques welcome there too.

Thanks!
