Generally speaking an electrician wouldn't be able to comment on certain manufacturers products, you would be better off speaking to an electrical wholesaler.

If you can't directly replace your MCBs for RCBOs you may be able to install a separate RCD alongside your consumer unit.

Be sure that any downlighters above the bath ar shower are suitably IP rated.
