PMP23454: Daisy Chain Of PMP23454

Part Number: PMP23454
Other Parts Discussed in Thread: PMP21999

Tool/software:

Dear TI experts,

I have the following requirements:

1. Input: 290V - 400V (DC)
2. Output: 200V, 20A
3. Requirement: CC, CV - whereby the CC is required because my load is a variable current sink, therefore my current reference will not be fixed. The CV is just to ensure OVP. 

Wondering if PMP23454 can be modified in the following way to fit my requirements 

Because of the LLC Topology, not sure if this daisy-chain is feasible.

The reason for this approach is because the development time given to my team is short - therefore it would be more practical to modify/combine tested and working designs to fit our requirements.
