Yes you can add the stacked resource later, I have done this same thing several times now by making the the device slightly larger first and using internal metadata.
Also I have a DR site using protocol C and pull-ahead enabled without using DRBD proxy. The main site and DR site are connected via cable modem connections (10Mbit up/ 20 down both sides). The only thing I have troubles with is if I need to add a large amount of data (50+ GB), which in my case is fairly rare (daily norm is ~2GB), then it can take days or weeks to sync up fully again. Also I used truck-based updates for the initial setup of ~1TB to avoid having to pull all that over the internet link.
