Not really, as FermaidK has all of the micro nutrients etc that energiser (presumably pure DAP) doesn't have - as I understand it, the energiser is just a straight source of nitrogen.
Where the suggestion is to do staggered nutrient additions, it seems that the idea is usually to add the GoFerm to rehydrate, then pitch the yeast, then when there's definite signs of fermentation, a mix of roughly 50/50 FermaidK and DAP is used - but often it's calculated for total amount, then half the total is added when the lag phase has finished (those signs of ferment mentioned earlier) and the second half of the FermaidK/DAP mix at the 1/3rd sugar break (oh and daily aeration of the must down to the 1/3rd sugar break as well).
I don't know if a mix of GoFerm and DAP would approximate FermaidK or not though. That might be worth thinking about unless someone has any specific reason why that might not be a good idea.......
