--install-with-src should include ipkg and ttm files. This would allow editor functions such as semantic highlighting and jump to definition when viewing source files of install packages. The ipkg may also have to be modified to have correct build and source directories.
I think a better approach would be to design a ttp binary file format that would contain
the relevant information from .ipkg
potentially some additional metadata that would be useful (e.g. a map of all of the exported names and the module they're defined in which could help with out-of-scope issues by suggesting the addition of missing imports)
