Well the main issue is that Subgroup is based on the nested set model for fast reads (and slower writes as a tradeoff). Theoretically it could be done if we made the tree metadata fields multi-value and tagged the same groups as belonging to multiple trees.
However, the entire module was built around the single tree principle and therefore this would constitute a significant rewrite of seemingly unrelated systems. Most of these rewrites would probably end up breaking BC, so it's likely that an entire new major version is needed for this functionality.
