How does Convertible Chassis work?

For reference, the feat's text is below:

CONVERTIBLE CHASSIS FEAT 14

Your drone easily converts into additional forms. Reconfiguring your drone into a different chassis is a 1-hour activity with the concentrate and manipulate traits. When you select this feat, choose one chassis as your alternate chassis (page 16). Your drone gains the Mobile Reconfiguration action.
Mobile Reconfiguration [2 actions] (flourish) Your drone reconfigures into its alternate chassis. It remains in the new configuration until you command it to perform this action again.

I have a few questions on how this works:

1. Do you get a second chassis immediately when you get the feat, and can change it as a 1-hour activity, or do you need to create the second chassis over the new activity?
2. Can you change your drone's original chassis?
3. Drones can choose whether they increase their size or not. This way, a small scout drone can stay small, but a big drone can grow into a huge mech. How does this interact with Convertible Chassis? In other words, if you chose to increase the size of your tank drone, does your scout chassis need to grow up as well?
4. Different chassis have different hit points. What happens when a drone changes its chassis to one that gets a different amount of hit points? Are any hit points lost or gained, or does each chassis have its own hit points?
5. It seems that any customizations and weapons don't change. But should they? For example, if you give your Tank Chassis drone Flier and Nightvision Sensors customizations and reconfigure the drone into Surveillance Chassis, you effectively lose those customizations.
6. Can you select the same chassis twice? You might want to just change your drone's size and leave other features as is. But an Imitator Chassis drone could swap between two ancestries in infiltration missions, for example.

A bit late to this, but answering the questions in order:

1. You get a second chassis immediately that you can command your drone to reconfigure into as a 2-action activity. This is in addition to being able to reconfigure your drone into any chassis as a 1-hour activity.

2. Yes, using the 1-hour activity.

3. This I think is perhaps where the rules are more ambiguous. I would personally rule that you choose the size for each chassis independently of each other.

4. This I think is also where there might be an oversight. I would personally rule that the two-action activity wouldn't change your drone's Hit Points, but the 1-hour activity would affect its maximum Hit Points without necessarily affecting its current Hit Points.

5. Indeed, this seems like an oversight as well, and I'd personally have liked it better if there were better accompanying means of changing customizations and weapons.

6. As written, yes!

Thanks for the thorough response!

Yeah, these things need clarifications. I think your rulings make sense, but I can also see others making different rulings. And it would be pretty important for players to know exactly how the feat works before they take it.
