I got bored while my kid took a nap (well, more like stuck inside due to freezing temperatures this morning), and did a quick edit of the MD-87 to create the MD90-10.
McDonnell Douglas originally imagined a family of planes for the MD-90 series, with the MD90-10 being essentially an MD-87 with 22,000lb thrust V2522-D5 engines in place of the original JT8D-200s. There were also plans for an even longer MD90-40 but with the same wing I doubt it would have handled very well.
I don't have an updated FDE for it and didn't create any specific PSD files for painting, but the MDL file is in an attached zip file and you're welcome to it, though I won't be providing much, if any, support.

"THANK YOU" Nick .... and nice to see you floating around here once again.
IF you'd care to supply myself, and Tony, with a bit more tech data concerning this particular aircraft variant .... THEN .... we'll see what we can do (if anything) with it .... and/or alternatively .... how we might even be able to best support you with it also
It was essentially just an MD-87 with V2522-D5 engines. It shared a few drag reducing enhancements with the MD90-30 but was, in essence, just a re-engined MD-87. V2500 engines are several hundred pounds heavier than JT8D-200s though so the empty weight would increase but it shared the same length as the MD-87 so forward ballast may have been necessary. Since it didn't actually exist I don't have any weight and balance specifics.
If I could find a drawing or rendering I'd like to do the Super 85 which was supposed to be powered by CFM56-3 engines. The CFMs were much closer in weight to the JT8D and wouldn't have required the fuselage stretch that the MD-90 needed. I would imagine that they would be in nacelles similar to the CF34 used on the CRJs though I can't be certain as CFM56s have come in nacelles of wildly different shapes over the years.

I've been thinking about trying to do something like this for the 717. Came across a page that had information on the 717 family (717-100x/-200/-300x). It has a lot of information on there. I didn't realize that McDonnell Douglas/Boeing planned an MD-95/Boeing 717 family. Same goes for the MD-90.
Didn't McDonnell Douglas have issues with the MD-90 wing during the beginning?

I don't recall wing issues with the MD90, but they had headaches with the engine pylons, thrust reversers, tail and tailplane... MD90 has moving flight controls on the engine pylons as a result, and the top of the tail was "squared" off.
This of course is not mentioning the problems with the electrical system, static/pitot system, landing gear metering pins, etc
