As this comment says, the boundaries for privileges at the low end, e.g., for up voting, flagging, down voting, etc., are likely more important to consider possibly changing. Now, by asking just one or two questions with some positive up votes, it'll be that much easier to get those privileges than before. I suggest considering increasing some of these, although I'm not sure what an appropriate amount would be.
However, one thing I think should be increased is for up voting. Also, as snakecharmerb's comment says, the threshold for "protected" questions should possibly be bumped up, say to 20, with the later comment making several good points in favor of this, e.g.,
... it not only stops very new users from adding low quality answers to popular questions, it also protects them from the consequences of doing so: downvotes and answer deletion. So upping the the protection limit would help new users onboarding experience I think. (Also, it would prevent the protection privilege, which requires 15,000 rep to earn - from being completely devalued.)
Also the minimum reputation of 5 for "participate in meta", can now be achieved even with a net negative score, so perhaps it should be increased to 10 or so as well, to make it more appropriate. Finally, if they're considering examining the reputation system, perhaps some privileges that are currently combined at one level, e.g., "Post more links, answer protected questions", should now have different privilege levels.
