YES!

There are lots of splitters out there that don't act as a proxy. I've personally build two of them, one fully manageable and protocol aware, the other extremely simple with only minimal intelligence.

The standard was specifically designed to allow for relatively simple inline devices such as splitters. Take a close look at the timing section of the standard, this is the reason you're allowed to shorten breaks for normal responses and to drop preamble bytes in the DUB response (among other accommodations).

Whichever route you go when you're designing a splitter, plan on spending a lot of quality time with your oscilloscope. Getting it "mostly right" is easy. Dealing with all the pathological corner cases is a whole lot harder.
