Can these filters improve on the nebulosity?

Hi David, it all depends what you expect
If you expect to see what you see in pictures here in iceinspace and elsewhere then you will be disappointed, the eye does not see the colours that you see in the pictures.
A 10" scope with a low to medium mag eyepiece will give you splendid views of the Orion Nebula.
There are a few things that can spoil you views, One is poor seeing ie, shimmering and fuzzy stars, light polution, and poor collimation.
A UHC filter will enhance your views of most Nebula and still give you some stars as well.
O111 filters are mainly good for Planetary Nebula , but they darken or even remove most of the stars.
There is one thing that will improve your observing and that is experience .
As you observe more you will begin to see more datail in objects like the Orion Nebula
