If that's the concern, I'd just carry the ones without a plug.
...but I don't think that it would be a big concern: the Goldilocks punctures that we're talking about seem to be pretty rare (I've had one in about 12k miles), the plug should hold air well enough that you can top it off to avoid bottoming out and, if you are low, the plug is small and not likely to be meaningfully/forcefully contacting the rim (it'd either be between the rim sidewalls or have a layer of tire between it and the sidewall, beyond that, you'd either need to be riding rim or have just awful timing, bottoming out at the exact time that the plug would be within the contact patch).
