I see no problem with it.
Ref to https://boostorg.github.io/build/manual/master/index.html#bbv2.overview.configuration

It just a matter of handling dependencies. If it required for target,
Boost libraries can be included in SDK.
Another option - drop Boost and replace it with something more lightweight.
If it's not possible, then go ahead with cross-compiling and static linking.
