The lower edge of the body of a highland jacket should drop no further downn thatn to just reach and maybe cover the sewn down portion of the pleats in the back of the kilt, known as the fell. If your non-highland jacket covers below that portion of the kilt when you wear it it will appear far too long for wear with the kilt. Generally a highland jacket's sleeves, with hands down at side, are give or take at right about the same height as the hem of the body of the jacket, whereas with a typical suit coat or sport coat/blazer the hem of the body of the suit can be inckes longer than the coat sleeve.
That jacket length difference, combined with the absence of proper room to display your sporran under the front of your non-cutaway jacket front will make for a very odd appearence indeed.
It has been done, and at lest semi-successfully by one or two members here, as we have seen the photos, but it is really the extreme rarity when it works. So I personally would not recommend it. It is up to you to decide what your reasoning for feeling the need to wear the kilt to this specific event, how important is it to go to the event in a jacket as opposed to a nice vest/sweater vest/sweater, and whether you have a spare jacket that you are willing/desiring to be cut down into highland length in order to fulfill typical highland dress appearence with the kilt. If you have to attend the event in a jacket and tie, unless you really need to wear the kilt for some specific reason, if you do not have a proper highland jacket to wear with it I would recommend you go in more standard pants that will look good with your jacket and tie, and work on future opportunities for highland dresswear as you also work on gaining appropriate jacket to wear with the kilt.
