Does a scooter count as 'redundant buoyancy'?

[Nick_Radov]

You're asking the wrong question. Redundant buoyancy isn't required, so whether you need a drysuit or scooter or something else for redundant buoyancy is kind of moot. What you actually need is a balanced rig, and it seems like you're at least close to having that. Although for tech diving in a wetsuit I would lose the tail weight and go with a regular weight belt that can be ditched in an emergency if you have a buoyancy failure at the beginning of the dive, when you're still carrying significant gas weight and haven't built up a major deco obligation.

That said, it's a good idea to carry an extra lift bag in order to give the team more options.

Well, with a scooter as redundant buoyancy, a spare air as redundant breathing supply, and split fins as redundant propulsion, I have only 3 words.

You’re gonna die.

I suspect using a scooter to hold deco stops for an hour or more might not be sustainable, if you're doing drift deco.
