Alright guys, after looking, the Innovia 200 will not work, even if there was another nose style put on, and I'll show you why. I dug up some research (basic searches) and got these measurements, which I'm sure will prove to be difficult in many places.
------------------------------Mark VI Monorail--------------------Innovia 200 Monorail
End Cars (with Cabs)-----40 Feet 5 Inches--------------------38.05 Feet
Regular Inner Cars--------28 Feet 2 Inches--------------------28.16 Feet
Train Width----------------8 Feet 4.5 Inches-------------------8 Feet 8 Inches
Skirt to Roof Height------10 Feet 5.5 Inches------------------11 Feet 2.5 Inches
Floor to Roof Height------5 Feet 10.75 Inches----------------7 Feet 1 Inch
Top Beam to Roof---------7 Feet 5 Inches---------------------7 Feet 10 Inches
These are just a few random measurements, that seem to be the most noticable... The Innovia 200s are a bit bigger... They may not be MUCH bigger, but they're larger, and I think that would prove to be problematic in areas.
If they were to get new trains, they'd have to be custom and fit the size they have now... I think in stations and the Contemporary the Innovias would NOT fit at all. The Mark VIs have like 4-6 inches under the floor platform above... Width I think serves a problem too at the Contemporary...
Long Story Short, GET TO DESIGNING DISNEY!! YOU WON'T BE ABLE TO USE INNOVIA 200s!!!
