Preposition stranding: is it possible to remove preposition altogether?

By removing the preposition you'd be turning an intransitive verb into a transitive verb. This may work in certain cases, because there are some verbs that can either be transitive or intransitive. However, the transitive and intransitive versions of verbs often have different meanings. In that case, removing the preposition may result in a valid sentence with a different meaning.

Examples:

The list to add [transitive] items to -> the list to which items are added
The list to add [intransitive] items -> the list whose purpose is adding items

The dropdown box to select [intransitive] items from -> the list from which items can be selected
The dropdown box to select [transitive] items -> the list whose purpose is selecting items

I need someone to talk [intransitive] to -> I require a conversation partner
I need someone to talk [transitive] -> I require that someone speak

The car must not be jumped [intransitive] on -> Don't climb on the car and jump on it
The car must not be jumped [transitive] -> Don't jump start the car/Don't leap over the car

The climbing wall should not be climbed [intransitive] on -> Don't use your hands and feet to move around on the wall
The climbing wall should not be climbed [transitive] -> Don't use your hands and feet to ascend the wall (hey, this one pretty much works!)

Put does not have a transitive sense, so a tray cannot "put fruits."
