Replacing original fuse panel

[fishstu]

On my 2001 20ft Seacraft MA looking to replace the original fuse panel that is tucked up out of sight in the console.
I am mounting the newer fuse type Blue Sea systems fuse panel higher (much more accessible) in in the top portion of the console which opens. A question I have is - To minimize wiring I want to replace the original fuse panel ( that has a neg bus) with a connection block to maintain the neg side of the circuit and use the new fuse panel with out a neg bus for the positive side of the ciruit.

Does this sound a good idea ?
Also should I get a blue sea fuse panel with neg bus any way ?
Any idea and advice very welcome
