Data Transformation in Transactional Replication

I already put this set of questions to another group and oly one person
replied. I would appreciate if other people can share their opinion as well.
Thanks
=====================
I have a transactional replication set up from one system to another.
Subscriber has only read mode on data (Uni-directional Replication). I need
to do lots of transformation in the data while replication from Publisher to
Subcriber Like adding the same record in the other table as well or do some
denormalization etc.
Which route should I choose?
1. Modify Replicaiton procedures to have this business rule in-built.
2. Should I create indexed views and other tables on reporting server.
3. Should I create trigger on the reporting server and have the replication
procedure only do the insert and trigger do rest of the business rules
implementaion.
4. Can reporting services be used for such a transformation.
5. Should I have DTS as a part of replication.

Perhaps you should call PSS and get their input.
