SLT will decluster this one the fly, I have a client using BSEG, KONV etc with no issue.
I wasn't clear on the original question however, do you already have SLT replicating BSEG and then the structure was changed and you are wanting to know the impact? Or are you referring to a new scenario where you want to start replication?
With the proper SP levels on SLT, both scenarios are supported.
