... would it be feasable to fly?
From the point of view of the lateral part of the routing, while it's good to stick to the standard routes in the SRD, pretty much anything seems OK on the FPL. The controllers will look at your exit point and you'll get vectored there with no regard for what you've filed in between.
In terms of levels, you'll be in the way at less than about FL80 in a lot of that airspace, so yes, you do need to climb to FL90 or FL100 most of the time. Bear in mind that airways levels are always round thousands (e.g. FL90 for that route).
