All you are doing is editing the part that someone else played, though, Donny... before you get ALL worked up about it.

Take a commercial SMF or style, and then part by part replace out completely the original with your own playing, and THEN you can lay claim to it being your OWN work...

OK, leave in the drums if you have to! Personally, I don't have good drummer chops, so if I edit a commercial file, I often don't do much more than add in a bunch of ghost notes and flams, etc., although the dynamics I jack around with a LOT...

Most commercial SMF's, styles and web-found stuff was all programmed before keyboards started having multi-velocity drum sounds. Tweaking those until the hit the cross points correctly is a lot of work, but worth it, IMO...

Sure, OK, spending ANY time editing SMF's and styles is perhaps more than a lot of people here do, but there is still a whole lot further you can take them, if you want to REALLY call them yours...
