It would be easy to use the SidecarBuilder to achieve this :)

I can take this on.

@prestwich Unfortunately using SidecarBuilder is not possible because it's in alloy-consensus while BlobTransactionSidecar is in alloy-eips, and adding a dep of alloy-consensus in alloy-eips creates a circular dep.

Do you think it makes sense to move SidecarBuilder to alloy-eips?

[prestwich]

yes i think that would make sense
