A688(PhXY): No. If a specific feat is required as a prerequisite, then that is the feat required. The only exceptions are spelled out in the feats (like expeditious dodge for dodge and stone power for power attack).
By RAI, you might be able to use Sudden (Maximize) to craft a Metamagic Rod of (Maximize) though, since you can create the effect the rod duplicates. DM-dependant of course so YMMV.
A689(ksb): Although the abilities are similar, wolverine's racial ability does not reference the barbarian class feature or say "this is otherwise identical to the barbarian's rage ability." Also the trigger is different, the limitations of actions are different(you MUST take an offensive action vs. the opponent that injured you, if able), there is no fixed duration and no bonus on will saves or fatigue afterwards. This many differences suggest the two abilities would likely qualify as separate sources despite the same name, and that the bonuses, penalties and limitations of both kinds of rages should stack while both are in effect.
From the perspective of balance, the benefits of wolverine rage are weighed by the downside that the player must actively engage the opponent that triggered the ability--even if the opponent is one that the player has no hopes of defeating by himself or if there is an enemy that is a higher tactical priority(the player is forced to attack the summon rather than the summoner, for example).
Q690: Is it perhaps time for a new thread for this topic? Almost 100 pages...
