It could be. Even as someone with no experience developing and shipping hardware of this type I can think of several issues it'll likely run into.

First and most damning is he's just Some Guy™ meaning he'll get fleeced on manufacturing and parts sourcing costs, so even if he made e.g. a kickstarter or indiegogo to fund properly-made units, they're going to be fairly expensive. Maybe not Vive tracker expensive, but certainly at a price that will cause people to think twice depending on overall performance.

Second, due to how they work, drift probably gets comparatively worse based on how far the sensor is from the headset, because he's using a skeletal forward kinematic model (e.g. if the hips are drifting, since the ankles compare their position to the hips, they will drift even more, etc.). I'm not sure if it'll be better or worse if you're not moving much, as I'm not super familiar with how good IMUs are at judging movement, but since they don't even reference off of each other via e.g. EM sensors like NoloVR uses then you can bet every little bit is going to compound.

Next is initial setup will be a pain since, based on how he explains it, they reference themselves off of a skeletal model you have to set up, which is then linked to the headset position to extrapolate the rest, this means you need to know not only how far each sensor is from the next (and in turn from the headset) you also need to make sure you wear them the same each time, or that creates additional inaccuracy.

Basically pretty sure it's gonna be jank regardless, and unless you like tinkering and already have a 3D printer or such, it's gonna be expensive and hard to buy, if it even makes it past an initial run via indiegogo/kickstarter at all.
