This would be far more difficult to overcome (having to cut around
75mm off a (presumably) 760mm wide door - so you'll either have to
contact the makers of the door to see if they will do a purpose made
one or widen the opening (if you can or want too) to fit the
smallest standard door width.

Strength issues apart, taking 75mm off the width is almost certainly
going to screw up the proportions of a four panel door. 686mm (2'3")
is a standard door width. The OP needs to go to a timber merchant or
door specialist.

More or less what I said I believe - and if the OP wants the same pattern
door with a non-standard width, then the manufacturer would be the best to
ask, as they may have the facility to make the odd non-standard door [1].
Just like the manufacturers of IG doors will do if asked.

[1] Or they may even start a 680mm (2' 3") range as this is also a
standard size, internal door used on may door sets.
