Make it level 40 and below. Limit the WvW rank to (insert number here). Make this an "Introduction to wvw" for lower levels, and a place for people who prefer to run 'base class' builds. Keep the current rewards for "winning" the 2 hour skirmish (Supply delivery to winning color home BL, I would up it to accommodate +5 but not +10) Offer the ability to Stop/Remove Wxp (Stop being free but Removal could/should have a cost associated, be in gold or wvw currency of Anet's choosing). Limit Siege to Cats, Rams, ACs and Ballista. (offer the ability to 'spec' for these by using the limited points gained while playing) There are plenty of 'details' that are missing, as this is merely an outline. I figure folks who get paid to work on this kind of thing, can handle that portion.
