Any new merkle algorithm should use a sum tree for partial validation and
Is there something special about 216 bits? I guess at most 448 bits total
means only one round of SHA256. 16 bits for flags would give 216 for each
Even better would be to make the protocol extendable. Allow blocks to
indicate new trees and legacy nodes would just ignore the extra ones. If
Bitcoin supported that then the segregated witness tree could have been
added as a easier soft fork.
The sum-tree could be added later as an extra tree.

The bridge would only need to transfer the legacy blocks which are coinbase
only, so very little data.

That is very true.
