I don't know about convert, but hgsubversion should be able to help.

I'd suggest converting every X.Y "project" separately first, check the conversion to be correct regarding branches and tags, then manually link them together by means of grafting commits. You can pull various repositories into one despite them being unrelated by means of the --force option.

I'd try hgsubversion before anything more complicated. You may need to
specify some config knobs to make it pretty, but it should be doable.

If you now pull 1.1, 1.2 and 2.0 via --force into 1.0, you will get 4 roots with 4 mainlines. You could then graft (or rebase) e.g. (1.1.1) and descendants onto (1.0.3), then (1.2.1) onto (1.1.2), then (2.0.1) onto (1.2.1). Doing so, only .hgtags might report conflicts, which are easily solved with simply taking both sides. After doing the operation, strip remaining old "mainlines" from the repo.
