We have a Pure Evoke 1 DAB/FM radio in the kitchen and the sound from the the built in speaker is not up to much.
The radio lives near a tall larder unit made of 18mm faced chipboard with slide out wire baskets and containing dried and tinned foods. For a quick and easy solution I was thinking about cutting a hole in the side of the cabinet and fitting a HiVi M3N or similar and driven by a class D amp.
Is this likely to work?

What kind of space; shape; volume??? You might be able to do a vented (bass reflex) full range. I use the free online calculators. Have you seen these before?
HiFi Loudspeaker Design
Pretty handy; especially the ones that let you compare between "optimum" and "custom" box size. There is one that lets you compare closed to vented box with the same driver; also handy. I have tried several Mark Audio MR drivers; Also; there are several Fostex drivers that might work here. These two brands would be a higher quality than HiVi. Do you have a set budget?

sorry, I meant FR, not MR...more coffee required to wake up the brain.

Without knowing cabinet dimensions it’s hard to say, here are a few things to consider...the things in the cabinet are not stuffing and are not inert or secured so calculating air space will be difficult and things inside the cabinet could rattle. You could build an appropriate sized MDF box without a face or divider to delineate airspace and place it was inside the cabinet but this might defeat the purpose
Well it's about 28l, but maybe a third to a half of that is occupied by food. Then there's the door, which is shaker style with a ply panel and simply hinged with no latch.
So all a bit crude - I did think it might be closer to an open baffle more than anything else.
It's only for the radio, so I'm not expecting super quality sound, just something less muffled and louder than what I have now.
The drive unit will point sideways - also not great!
And there's no room to build a cabinet inside a cabinet.

If it is possible...could you find another identical food storage unit, like the one you already have? Then, it really shouldn't be that difficult to "seal-up"(strengthen) the new unit, with a simple matching color fabric grille...the radio in the middle, flanked by both same sized, same color, dimension objects??
The Visaton six & a half inch full-range driver(BG17-8) is exactly at 28 litres (your approximated size) for a tuned vented enclosure...this driver is at 93 Db, F3 of 73 hertz, a rating which is undoubtedly way way more sensitive than the built in driver.
Just my two-cents
