WHAT? Only 10k, and he wants to file? You're right, he's not stable.

There are people out there that owe close to 500k, and only then are they finally thinking about filing. (Actually, hardship will probably have more to do with it than an outstanding balance.)
Also, I don't think it's true that they hurt your score equally. I don't have any details handy, but I'm fairly certain bankruptcy will hurt him harder and for many more years than being delinquent.
Finally, loan consolidations in itself will not hurt your credit. Assuming that your cousin qualifies, it merely lumps several different debts into one large one. Assuming that the consolidation loan's interest rate is reasonable enough, and your cousin can start paying it on time, then he shouldn't have to worry much, especially 10k.
Either that or I'm in really, really deep doo-doo with my 27k.
