I'd get a fibre adapter plate then, you'll see that it is simply a plate with holes that hold the couplers in place and usually clip them on the back side. Technically the same as just using couplers but a bit more secure and protected from accidental damage.
Or you could go the whole hog and resplice the fibre into a panel if they are multicore fibres, that way you could convert to LC if you prefer.
