It looks like it would be challenging for most people. Those parts F18 and F19 are a good example of the reason why: they look like something else sits against them, but they get installed "in a vacuum" here without any way to really see if they're right or not. Takom also has a habit of making you do this, and I think the only real solution is to have enough experience to see this is probably not going to work. (I use the instructions mostly to tell me where parts go, not in which order to assemble them.)
