Nothing unusual. The hard work of the bankruptcy is over. it is not that unusual for the trustee to name new Counsel near the end. The original counsel, assuming she is still at the firm, has other, more urgent cases, that demand her attention and expertise. So 2 members of the same law firm were named to just finish off what little is left so they can handle it when they have time.
It is a Chapter 7 - liquidation. These cases move very slowly, so time with trustee's counsel is often an issue, especially at the end of the process.
I certainly would not read anything into it.
