I think it is impossible. Because phpbb team will probably take care how to create output suitable for PS and probably this output will be unable to optimize for other styles.
Users, skilled in XHTML/JS/CSS enough to support SS2 probably will no do that. Because they using phpbb not because they have time to have fun, but because they require it. They able support SS2 at level of their requirements independely, but they probably will never take care to lose time to share their work to other part of community.
How do you think phpBB came to exist or continues to be developed? There is no phpBB headquarters. There is no staff, no payroll, no official organization or corporate entity. It is entirely community-based, developed and maintained by people willing to volunteer their time and energy to the effort. Actual phpBB users have become phpBB developers:
The phpBB teams are made up of people from around the world; a tribute to the diverse audience of phpBB™ itself.
Bottom line, if there are style authors willing to make subsilver2 based styles, there will most certainly be style authors willing to perpetuate subsilver2 itself. It would be easy for any competent style author to port future prosilver style updates over to subsilver2 styles
