Re-use the TREASURY_PALLET_ID for now. TREASURY_PALLET_ID defined to be same thing anyway:
PalletId(*b"py/trsry")

Sounds fine. The local fees can all go to the common treasury account for BridgeHub.

Our other pallets on BridgeHub have all standardized on using this function for converting sibling para_id's into sovereign accounts:

Just a note here, I tried to do this in multiple ways but the traits contraints bled out into the implementations of control pallet, outbound queue, benchmarks and tests. So in the end I decided to just copy the function and create a test that makes sure the outputs are always the same.
I tried changing from T::AcccountId to plain AccountId but then some scale codec traits were required on our pallets and then bled into the benchmarks which are generated by macros and cannot be applied there.

Since we're going to use this type in about 5 different BridgeHub runtimes, lets move it to a new crate named snowbridge-runtime-common, located in our own Snowbridge repo, in this directory: parachain/primitives/runtime-common.
Then we can the runtimes depend on our runtime-common crate.
