OIII and Ha alone on the trunk should produce a nice image

Many go further and add SII but HOO is still very nice on many targets like the trunk neb.

By and large I think you can expect similar to other nebulae imaged in HOO, where the hydrogen looks red-pinky and the oxygen adds a blue and pale hue to certain regions.

I am not very good at HOO processing as I think for some people there is some wizardry involved to give it that extra edge but I think you'll probably be pleased with your results if you go for HOO here!

Agree.  Add Sii when you can as it will give you more options.

I agree HOO on the Elephant Trunk can be tricky to get a pleasing colour.

I recently spent more time on getting the colour blend to my satisfaction than the actual post processing!

You can also spend more time on the post-processing than the actual capture as well.
