The fact that you choose to use more restrictive regs is only relevant internally. For example, 135.101 does not apply because you are not flying passengers.
Using Boutique as an example, I would bet that because it's all subsidized flying the empty legs are still 135. I don't know for sure, but that's my guess.
We were assigned different flight numbers for 91 legs.
