... I would be glad to share the route we are planning if you are interested.
No problem in sharing the route. Since the GART is almost complete in the east of the US, say from Washington-DC to halfway Nebraska, I find it a bit odd that you only embark on it far to the west, probably from Missoula.
There is an old saying among hikers on the AT - Hike you Own Hike, and I think the same rings true for bike touring - ride your own route. That being said here is why I have decided on the route that we are doing.
According to their website today
https://www.railstotrails.org/greatamericanrailtrail/route/ the GART route is about 52% complete.
The preferred route of the Great American Rail-Trail connects 145+ existing rail-trails, greenways and other multiuse paths spanning more than 3,700 miles. These trails are hosting the Great American through their communities, making possible this grand vision of a nation connected by trails. And with more than 52% of the route already on the ground, now is the time to experience the Great American Rail-Trail!

https://www.easternexpressroute.com/you will see that it utilizes the C&O, GAP, KATY Trail, and a few others along the way. As I researched each trial on the GART individually, I also found that some were more for mountain biking, and even though they exist today, they are not suitable for travel on a loaded touring bike - the eastern P2C is a perfect example. Also the Eastern Express route does not zig-zag north and south for the sole purpose of staying on existing trails. Like I said, my original intent was to follow their trail but from midway in Iowa to the Columbia River the trail is still a concept for the most part. The Ohio sections that I will miss will most likely be a week long trip of its own with my wife later on. I really have no desire to get as far North as Chicago or ride through Pittsburgh again. That was one of the things I was not fond of with the GART - many of their routes take you close to urban sprawl. I have lived on the East Coast, the West Coast, and even on the Gulf Coast, and have seen enough of suburbia. I want to ride the open areas, the deep forests, avoid major metros and spend time in the heart land where you can still catch a glimpse of the America I grew up in.
