Fan Blade elimination on slant 6

Is there a way to eliminate the use of the fan blade on a slant 6 and use the electric type fans for cooling the engine? I know when some people do their mods, they get rid of the fan blade assy. on bigger block motors, but not sure if the same could be done for the slant 6.
What would be involved in doing the swap if it can be done?

Any input is helpful.
