Your wisdom and experience is appreciated
I am told I am very direct, so bear that in mind.
First, you won't be around to care what anybody does with your trailer after you're gone, so make modifications you want, in order to enjoy it as you see fit.
To remove the toilet and replace with a household toilet, you'll need to remove the black tank, and plumb the toilet direct. While you're doing that, you'll also have no need for the grey tank, since you'll be connected to offboard sewer. Remove that, as well. You can connect the grey and black with a PVC or ABS Y, and send both off to wherever you're sending them.
If your heirs express an interest in keeping and using the trailer as a camper after you're gone, and you want to be considerate, save the holding tanks and connectors, and give them to the heir of your choice to store for their future use.
