Yes Ted, there is just that sort of jacket.

The Argyle style Jacket is just a style that refers to one with Gauntlet cuffs, Scalloped & buttoned Pocket Flaps, and epaulets.

If those are left off you have a very nice looking modern day wear jacket.

Matt at The Scottish Tartans Museum carries a Harris Tweed version. His Jackets are a bit less tailored than an Argyle and similar in cut to a sack coat.

I designed a Jacket of the type similar to what you describe too. I made mine a bit more form fitting in the back and sides.

Basically what you would have is an Argyle without all the fancy stuff.

The only difference I can see in your description and the Jackets out there is the cut away in the front for the sporran. If I read correctly you asked for no cut away. If this is so then no, there is no ready made jacket like that. But if you are willing to have the cut away I know of at least these two examples for you.
