Bifurcating Channels of inkjet Printhead cause any problem to the Printhead?

My Epson 9900 is idle most of time for want of art printing jobs, which it was used for, apart from Black alone printing to print Positives.
Now, I am buying a new Printhead.

There is an advice to bifurcate the 11 Channels into 3 groups: 4 for running CMYK color prints, 4 for printing Sublimation prints and 3 for Black alone printing.

Well, this way, if it works without problems, it increases productivity of the printer.
But, is it advisable, or cause problems to the Print head ?

Kindly advise. Thanks for the time...
