Arrow Switching Bow

The mechanic could be changed for the normal bow, or a new bow could be made with it.

So basically this new mechanic works like this.

When you have your bow out, it shows the arrow you are using in the bottom left. Using a specific key bind, you can switch the type of arrow (Spectral/Tipped). This allows you to effectively and non-intrusively switch tipped arrows in your bow.

Once the bow has started to pull back, you can no longer switch arrows though.

It's up to the devs whether to make a "switch-bow" or to just add this mechanic to the normal bow.
