Planting Fan-trained gage and peach trees in the same trough

[Llamas]

OH and I are moving to deepest Suffolk and I’m considering talking along a few of my newly planted trees. It's a new job that moving us and well be renting for however long we stay before one day moving back to the family farm where we live currently. We’ll be taking a few decommissioned metal water troughs in which I currently grow fan-trained peaches and nectarines. They’ve currently got a whole trough to themselves but to maximise space I’m wondering how good an idea it will be to try and squeeze in a peach and an Imperial gage tree into one trough, one at either end. Compared to most pots these things are huge but being new to it all I’m wary of pushing it too far and killing my precious trees.

I've attached photos of the trough with a wellie to help with scale, currently occupied by said peach and some easy access herbs.

Precautionary tales or words of advice?

Put as many as you like in a pot - they'll simply compete with each other, being smaller as a result. If they are on dwarf rootstock they'll appreciate fertile soil/compost, but, on the other hand, their dwarf roots will probably be quite small and not interfere with each other.
They may actually fruit better with some competition - as long as they aren't starved, or one dominating.
