Your thoughts on adding a humidifier to an Electric furnace with heat pump ?
I wouldn't think it would evaporate as much, there for not work as well as if it were on gas or oil.

What kind of humidifier?
If you're talking a bypass, you're correct, most likely it will work, just not as good as it would on a furnace.
The best option for heat pump would be a steam humidifier.

would the moisture content from the steam cause harm to the elements ?

keep in mind that with a heat pump system the unit will typically cycle for a longer period than with fossil fuel. Even though there is a lower discharge temperature the added cycle time helps to offset this. You can achieve acceptable levels of humidity with a conventional humidifier, either bypass or fan-powered. Ideally, you want to place the humidifier on the supply plenum so that you get the warmest air across the media. Talk to an HVAC professional even on an accessory such as this. Something as simply as the way the controls are wired can cause problems with the heating if not done properly.
All the best, John.
